Subsequence and Bitwise &

CodeChefOpen on judge ↗

You are given a list $A$ of length $N$ of non-negative integers. You need to find the length of the longest subsequence of $A$ such that the binary representation of [bitwise and](https://en.wikipedia.org/wiki/Bitwise_operation#AND) of all of its elements contains at least $K$ set bits. ### Input - First-line contains the number of test cases $T$. Then the test cases follow. - Each of the test c
