Efficient algorithm to calculate the most right non-zero digit of a number's factorial in Python Question: Calculate the most right non-zero digit of n factorial efficiently I want to calculate the right most digit of a given number’s factorial and print it. What I’ve done so far is: import math n = int(input()) fact = …
Increasing recursion fails with: Process finished with exit code -1073741571 (0xC00000FD) Question: import sys sys.setrecursionlimit(1000000000) def F(n): if n == 1: return 1 if n > 1: return n * F(n – 1) print(F(2023)/F(2020)) When the recursion is increased with setrecursionlimit, the following error is returned. Process finished with exit code -1073741571 (0xC00000FD) But without …
C programming recursion segmentation fault Question: I am trying to using with recursion function. But I got failed which is segmentation fault. #include <stdio.h> int factorial( int x ); int main(){ factorial(4); return 0; } int factorial( int x ){ return x* factorial(x-1); } I have seen the same code in Python and C programming …
How can I make my recursion program to output factorial of a number more efficient? Question: I have made a program which outputs the factorial of a number by calling the function: factorial() which uses recursion to calculate and return the value. I have also included a loop to break the program when the User …
Why is a factorial recursive function iterating from lowest to highest number and not from highest to lowest number? Question: I have this simple recursive function, which is calculating the factorial of a number. The result is good and it works like a charm. def factorial(y): if y == 0: return 1 elif y == …
Is there anyway to optimise this program further? Question: I’m writing this program to calculate a basic equation involving factorials, which is being tested on an online server. The equation is (1/n!) * (1!+ 2!+ 3!…n!). The program runs fine and gets the job done, however for testcases where n>1000 it runs slowly and causes …
Using primitive operators to find factorial of N up to K depth Question: Having difficulty coming up with a solution using: iteration/control-flow and accumulation. More than just a solution, would prefer having an answer with hints and explanation. def falling(n, k): """Compute the falling factorial of N to depth K. >>> falling(6, 3) # 6 …
How to calculate factorial in tensorflow? Question: I am new to tensorflow, I am trying to find a function that calculates the n!. I saw that one can use the gamma function, which was possible with theano, but did not work for tensorflow. factorial = theano.tensor.gamma(v) I am using a for loop to multiply number …
Take the Sigma of a factorial with unknown variable (using sympy?) Question: Good day, I am trying to write a function for the following equation: Where B and N are given and I am solving for A. I was reading up and it seemed like sympy was the way to go so I started to …
Python, count the trailing zeros within a factorial Question: I am trying to calculate the number of trailing zeros in a factorial. def count(x): zeros = 0 for i in range (2,x+1): print(i) if x > 0: if i % 5 == 0: print(“count”) zeros +=1 else: (“False”) print(zeros) count(30) I think the number of …
