Outputting height of a pyramid

Let’s think by other way:

Each row in the pyramid is the ‘row’ above + 1 and when finishing all rows then the sum of all rows are equal or ‘bigger’ which is the total number of blocks.

So, if you try by this method you have the follow code:

blocks = int(input("Enter number of blocks: "))
height = 0
by_row = 0
total = 0
for i in range(blocks):
    if blocks <= total:
        break
    height += 1
    by_row += 1
    total += by_row

print(f"The height of the pyramid:{height}")

So, it runs how you want but neglects the "Complete rows" part.

Note that the sum of block with n rows is n*(n+1)/2. For a matching block number floor(sqrt(2*x)) will give the correct result, with other numbers it can be 1 to large, so put the result into n*(n+1)/2 and if it is too large reduce by 1.

Height=floor(sqrt(2*x))
if(x<height*(height+1)/2) height=height-1

If the blocks number is 6, the height is 3. But if the blocks number is 7, the bottom will be placed with 4 blocks. So the height will be only 2. Because 4+3 is 7.

If the blocks number is 20, the height will be only 5. Because the bottom is 6, and 6+5+4+3+2 gives us 20. And the height is only 5.

Here is the code:

blocks = int(input("Please input block numbers: "))

my_dict = {}

for num in range(1, blocks+1):
    my_dict[num] = (1 + num) * num / 2

for index, value in my_dict.items():
    if value == blocks:
        print(f"The height is {index}")
        break

    if value > blocks:
        _sum = 0
        bottom = index
        for num in range(index):
            _sum = _sum + bottom
            bottom -= 1
            if _sum >= blocks:
                print(f"The height is {num+1}")
                break
        break

Hope it helps.

A pyramid with height n has 1 + 2 + … + n blocks. That’s also (n^2+n)/2.

Can you solve from here? You can use the function.

blocks = int(input("Enter the number of blocks: "))

height = 0

inlayer = 1

while inlayer <= blocks:

    height += 1
    blocks -= inlayer
    inlayer += 1

print("The height of the pyramid: ", height)

Here’s what I came up with because while building the pyramid if the remainder of the blocks are not sufficient you cannot complete the next/final layer/row.

Here’s the code:

blocks = int(input("Enter the number of blocks: "))

height = 0

rows = 1

while rows <= blocks:

    height += 1
    blocks -= rows
    if blocks <= rows:
        break
    rows += 1

print("The height of the pyramid: ", height)

blocks = int(input("Enter number of blocks: "))

for n in range(blocks): 
    if n*(n+1)/2 <= blocks: 
        height = n

print("The height of the pyramid is:",height)

blocks = int (input("Enter the number of blocks: ")
height = 0
min_blocks = 0

for blokken in range (1, blocks + 1):
    if ((min_blocks + blokken) <= blocks):
        min_blocks = min_blocks + blokken
        height = height + 1
print ("The height of the pyramid: ", height)

sum = 0
block =int(input()) 
for height in range(1,block):
    sum = sum+height
    if(sum == block):
     print("the height of pyramid:",height)

blocks = int(input("Enter the number of blocks: "))

height = 0
inlayer = 1
while inlayer <= blocks:
 height += 1
 blocks -= inlayer
 inlayer += 1

print("The height of the pyramid:", height)

I set the count variable to count the height. When only the blocks variable is greater than or equal to 1, it runs the while loop.

In the while loop, there are conditional clauses to be separated from when blocks == 1 and others. In the condition of the others, count plus 1 for each iteration and set total variable as the normalized blocks to compare with the user-inputted blocks. When total is equal to blocks, height is count and escape while loop. Else if total is greater than blocks, height is equal to count - 1 and escape while loop.

blocks = int(input("Enter the number of blocks: "))
count = 1

while blocks >= 1:
    if blocks == 1:
        height = count
        break
    else:
        count += 1
        total =0
        for i in range(1, count+1):
            total += i
        if total == blocks:
            height = count
            break
        elif total > blocks:
            height = count -1
            break

print("The height of the pyramid:", height)

hello guys this solution using both (for & while) loop

Using for loop

blocks = int(input('Enter number of blocks:'))
j = 0
for i in range(1,blocks):       
    j = j + I
    if j > blocks:
        i = i-1
        break    
    height = I
    print("The height of the pyramid:", height)    

Using while loop

blocks = int(input('Enter number of blocks:'))
j = 0
i = 0
while i < blocks:
    i = i + 1
    j = j + I
    if j > blocks:
        i =i-1
        break    
    height = I
    print("The height of the pyramid:", height)

This is the best solution that I could derive:

blocks = int(input("Enter the number of blocks: "))                      
                                                                         
height = 0                                                                                                                              
while height < blocks:                                                   
    height += 1                                                          
    blocks -= height
                                                   
print(height)

To begin with the total is 0 so if a user inputs say 6 blocks, definitely blocks are more than total in this case the else part executes.

The else statement keeps counting the height and summing it up to the total until it reaches the total number of blocks. It sums up the height because the row below is always height+1: So what is basically happening is this: 1+2+3+….+n .

And The if block helps us to exit the loop. "blocks <= total" , the less than (<) is because if the blocks are like 2 they are not enough to build a pyramid of height 2 so it should print the height as 1; so total should be less or equal to the blocks.

Hope this helps.

blocks = int (input("Number of blocks: "))
height = 0
total = 0

#loop until there are no more blocks    
while blocks:
   #this is the base condition which tells us when to exit the loop
   if blocks <= total:
      break
   else:
      height += 1
      total += height
print("Height is: ", height)

blocks = int(input("Enter the number of blocks: "))
y = 0
x = 0
for x in range(0 , 99999999999999):
     if  y == blocks:
        height = x
        break
     elif y > blocks:
        height = x - 1
        break
     else:
        y += x  + 1
        height = x - 1
print("The height of the pyramid:", height)

Let,
h -> height of the pyramid
n -> number of blocks

h can be calculated using the equation h = (-1 + sqrt(1 + 8n))/2. (Remove the floating value and consider only the integer part)

If you are intrested how the eaquation is derived, here is the explanation.

Here is the equation to calculate the height of a pyramid of n blocks :

h(h+1)/2 = n

Simplify the equation.

h^2 + h = 2n

Transforming it into quadratic equation of the form aX^2 + bX + c = 0, we get :
h^2 + h -2n = 0

Comparing h^2 + h -2n = 0 with aX^2 + bX + c = 0 we get :a = 1, b = 1, c = -2n

Put these value in the quadratic formula X = (-b + sqrt(b^2 – 4ac))/2 (Ignoring -ve solution).
So,
h = (-1 + sqrt(1 + 8n))/2 -> final eqaution to calculate the height of pyramid with n blocks.

Rest is simple programming.

PS: sqrt stands for square root.

First, I created a new variable called "Height" and assigned it with the value 0.

Then I created another variable called "Levels" to track the blocks used on each layer of the pyramid. I also assigned it a value of 0.

Why?:
The "Level" variable is necessary for use in comparing left over blocks to the last layer of the pyramid. Example – If you have 10 blocks left and your last layer was 10, you cannot create another layer because each one is supposed to have 1 block more.

When the variables "Level" and "Block" are the same, the loop is broken.

blocks = int(input("Enter the number of blocks: "))
height = 0
levels = []

while blocks > 0:
    height += 1
    blocks -= height
    levels.append(height)
    if blocks <= levels[-1]:
         break

print("The height of the pyramid:", height)
print(levels)
print(blocks)

I’ve come with this solution. I think is fairly simple, but does attend to the solution.

We have the height starting at 0 and the blocks_out variable, which is every block that is added to the second, third, fourth… level of the pyramid.

So I made a while loop, which will stop when the number of blocks stay equal to the height meter or below it. It will prevent that the program complete a level without having enough blocks to do it. If it has, then the height will be under block’s quantity and it will be able to complete a full level.

blocks = int(input("Enter the number of blocks: "))

height = 0
blocks_out = 1

while height < blocks:    
    blocks = blocks - blocks_out # blocks diminish, beginning with the first top block
    height += 1                  # put first block, first level done
    blocks_out += 1              # adittional block to each level that comes after


print("The height of the pyramid:", height)

When you invert your pyramid, you’re simply counting from 0 (height 0) and incrementing by 1. This also corresponds to the maximum blocks for each "inverted" level.
So:

• inverted height 1: 1 block (maximum)
• …
• inverted height n: n blocks (maximum)

Using a while loop, this looks like a simple solution:

blocks = int(input("Enter the number of blocks: "))
height = 0
while blocks > 0:             # as long as there are blocks
    if blocks - 1 >= height:  # remaining blocks vs number needed to fill the height level
        height += 1           # height is same as number of blocks in "inverted level"
    blocks = blocks - height  # remain after level completion
print("The height of the pyramid:", height)

Understand the logic:
At the top, we have 1 block so the height is 1.
The second level will have 2 blocks.
Thrid level will have 3 blocks… and so on.

1st level- 1 Block
2nd Level- 2 Blocks
3rd Level- 3 Blocks

blocks = int(input("Enter the number of blocks: "))
layer_block = 0
i = 1
height = 0
while True:
    layer_block = layer_block + i
    i = i + 1
    if layer_block > blocks:
        break
    height = height + 1
print("The height of the pyramid:", height)

For this coding exercise, I simply had a top to bottom approach by increasing the each blocks layer by layer.

blocks = int(input("Enter the number of blocks: "))

height = 0

while blocks > height :

  height +=1
  blocks = blocks - height

print("The height of the pyramid:", height)

n = int(input("Enter the number of blocks: "))
height=0
i=0
while n>i:
      i+=1
      n=n+1
      height+=1 
print("The height of the pyramid:", height)

thank you

Give this a try: Kept it as simple as possible.

height = 1
totalBlocks = 0

blocks = int(input("Enter the number of bricks:"))

while totalBlocks + height <= blocks:
    totalBlocks += height
    height += 1

print("The height of the pyramid is:", height - 1)

VERY new to IT… python is the first language I’m learning, but I’m pretty sure this works:

height = 0
width = 1
next_width = 1
        
while blocks >= next_width:
    blocks - width
    height += 1
    blocks -= next_width
    next_width += 1
           
print("The height of the pyramid:", height)

logic is putting an object in increasing order where top-level contains 1 and top-1 contains 2 and so on..Here passing array length and count=1 logic behind recursively call the same method until n>=count. For 1st call n=4 and count=1,for 2nd call n=3 and count=2 , for 3rd call n=1 and count=3 here condition fail and we return count-1.

/*Given n objects, with each object has width wi. We need to arrange them in a pyramidal way such that : 
    Total width of ith is less than (i + 1)th.
    Total number of objects in the ith is less than (i + 1)th.*/
public class Max_Height_Pyramid 
{
    static int pyramidHeight(int n,int count)
    {

This is what i used and it worked great try yourself 🙂
and it was fairly easy to understand.
