Can you solve this real interview question? Prime Number of Set Bits in Binary Representation - 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 represen
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 Explanation: 6 -> 110 (2 set bits, 2 is prime) 7 -> 111...
