Given two integers x, and y return the number of positions where their values differ in their binary representations as a 32-bit integer.
Constraints
0 ≤ x, y < 2 ** 31 https://binarysearch.com/problems/Hamming-Distance
Input
95Output
2Explanation
9 in binary is 1001 and 5 in binary is 0101, so indices 2 and 3 are different.
Given two integers start and end, return the bitwise AND of all numbers in [start, end], inclusive.
You are given three positive integers a, b and target. Consider an operation where you take either a or b and update one of the bits to 1 or to 0.
You are given a list of integers nums and a two-dimensional list of integers queries. Each element in queries contains [i, j] and asks what is the value of n...
You are given a list of integers nums where each integer occurs exactly three times except for one which occurs once. Return the lone integer.
