Given a range where 0 <= m <= n <= 2147483647 (32 bit), return the bitwise AND of all numbers in this range, inclusive. Example 1: Input: Output: 4 …
Write a function that takes an unsigned integer and returns the number of ’1′ bits it has (also known as the Hamming weight). For example, the 32-bit integer ’11′ …
Reverse bits of a given 32 bits unsigned integer. For example, given input 43261596 (represented in binary as 00000010100101000001111010011100), return 964176192 (represented in binary as 00111001011110000010100101000000). Follow up: If …
