3677. Count Binary Palindromic Numbers

LeetCodeMathBit ManipulationOpen on judge ↗

You are given a non-negative integer n. A non-negative integer is called binary-palindromic if its binary representation (written without leading zeros) reads the same forward and backward. Return the number of integers k such that 0 <= k <= n and the binary representation of k is a palindrome. Note: The number 0 is considered binary-palindromic, and its representation is "0".
