762. Prime Number of Set Bits in Binary Representation

LeetCodeMathBit ManipulationOpen on judge ↗

Given two integers left and right, return the count of numbers in the inclusive range [left, right] having a prime number of set bits in their binary representation. Recall that the number of set bits an integer has is the number of 1's present when written in binary. - For example, 21 written in binary is 10101, which has 3 set bits. Example 1: Input: left = 6, right = 10 Output: 4 Explanat
