You are provided with a non-negative integer n. Your task is to produce an integer array ans of length n + 1 such that, for every i in the inclusive range [0, n], ans[i] equals the total number of 1 bits present in the binary representation of i. Examples Example 1 Explanation: The binary forms: 0 → 0, 1 → 1, 2 → 10, 3 → 11. Their respective set‑bit counts are 0, 1, 1, and 2. Example 2 Explanation: For i = 4, 5, and 6, the binary strings are 100, 101, and 110, which contain…
