Count Set Bits in a 32-Bit Integer

Number of 1 Bits Easy · Topics · Company Tags · Hints You are given an unsigned 32‑bit integer n. Compute its Hamming weight — the count of bits that are 1 in the binary representation. You must not call any library function that directly performs population counting. Try to achieve a time complexity of $$O(32)$$, or better still, $$O(k)$$ where $$k$$ is the number of set bits in n. Example 1: Explanation: The binary representation of 128 is 00000000000000000000000010000000,…
