How to replace the independent 1 with 0 in binary number using only bitwise operations? Question: By "independent 1" I mean 1 that has no other 1 next to it ("010" or "10" and "01" at the ends of the num.) If the 1 doesn´t have any 1 next to it, it will change to …
how to make binary to bit 8 in python Question: i have variable contains with binary with type int ([101, 1101, 11001]) but i want to xor it with another variable, so i must change to string and add "0" so it has 8 number example 101 it’ll become 00000101 i was trying change int …
How does python perform bitwise operations to store three values in an int? Question: For example, if I have an int with a length of 32 bits, how do I store value A in the first 16 bits, then store value B in bits 17-24, and value C in bits 25-32? And how can I …
How can we decide that an integer is power of 2 by using bit manipulation? Question: For example if the given number n = 16 If it is power of 2 then the output should be true else false, i want the answer by using bit manipulation. Asked By: Kushal_Hemanth || Source Answers: Does this …
Bit Manipulation, find another shortest array whose binarian is same as the given array's binarian Question: Given an array A, its binarian(A) is defined as 2^A[0] + 2^A[1] + …. 2^A[n]; Questions asks to find anther shortest array B whose binarian(B) is same as A’s. For example, A=[1,0,2,0,0,2]，thus if B=[3,2,0], this satisfies the requirements, and …
Parsing Yann LeCun's MNIST IDX file format Question: I would like to understand how to open this version of the MNIST data set. For example, the training set label file train-labels-idx1-ubyte is defined as: TRAINING SET LABEL FILE (train-labels-idx1-ubyte): [offset] [type] [value] [description] 0000 32 bit integer 0x00000801(2049) magic number (MSB first) 0004 32 bit …
How to create an array of bits in Python? Question: How can I declare a bit array of a very large size, say 6 million bits? Asked By: zheric || Source Answers: from bitarray import bitarray a = bitarray(2**20) You can check out more info about this module at http://pypi.python.org/pypi/bitarray/ Answered By: SJP The bitstring …
Python: Extracting bits from a byte Question: I’m reading a binary file in python and the documentation for the file format says: Flag (in binary)Meaning 1 nnn nnnn Indicates that there is one data byte to follow that is to be duplicated nnn nnnn (127 maximum) times. 0 nnn nnnn Indicates that there are nnn …
Python Number Limit Question: I know in most, if not all programming languages, integers, floats etc all have a maximum amount they can hold, either unsigned or signed. Eg pascal’s int type can only hold up to 32768 ~. What i wanted to know was, what is the limit on python’s int and floating point …
Typecasting in Python Question: I need to convert strings in Python to other types such as unsigned and signed 8, 16, 32, and 64 bit ints, doubles, floats, and strings. How can I do this? Asked By: user46646 || Source Answers: Python only has a single int type. To convert a string to an int, …
