A character in UTF8 can be from 1 to 4 bytes long, subjected to the following rules: For 1-byte character, the first bit is a 0, followed by its …

Given an integer, check if its binary representation are containing the alternating bits. For example, 101, 10101, 1010 are binary numbers with alternative bits. But 1011, 1110 are not. …

Question: Write a function to compute the number of bits required to convert a integer to another. For example, Input 29 (or 11101), 15 (or 01111) the output is …

This is another classic interview question: You are asked to write a function (in C/C++) that determines the number of bits required to convert one integer to another. The …

Given two 32-bit integers N and M, write a function to replace N (between bits position i and j) with M, so M becomes a substring of N located …
