Bitwise or of two numbers in c++
WebMar 25, 2024 · Naive Approach: The simplest approach to solve this problem is to iterate up to the maximum of X and Y, say N, and generate all possible pairs of the first N natural numbers. For each pair, check if Bitwise XOR and the Bitwise AND of the pair is X and Y, respectively, or not.If found to be true, then print the Bitwise OR of that pair.. Time … WebJan 13, 2024 · Try It!

Changing the nth bit to x. Setting the nth bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n);
