CodeChefOpen on judge ↗
Given an array $A$ of size $N$ containing $N$ integer numbers. Also given $Q$ independent queries. In each query, you are given three numbers $L, R$ and $K$. Tell if you can choose $K$ integers between the indices $L$ and $R$ (both inclusive) in the given array such that the bitwise AND (represented by '$\&$' in C language) of the $K$ integers chosen is greater than $0$. ###Input: - Firs
