A Boolean Array Puzzle | GeeksforGeeks
Input: A array arr[] of two elements having value 0 and 1
Output: Make both elements 0.
Specifications: Following are the specifications to follow.
1) It is guaranteed that one element is 0 but we do not know its position.
2) We can’t say about another element it can be 0 or 1.
3) We can only complement array elements, no other operation like and, or, multi, division, …. etc.
4) We can’t use if, else and loop constructs.
5) Obviously, we can’t directly assign 0 to array elements.
