Better XOR

CodeChefOpen on judge ↗

Well after great research, research scientist came up with an xor algorithm but some of the students think that this code can be optimize better. Are you one of them ? Consider an array $A$ with size $N$. function betterXOR ( array A [ ] , N ) { ans = 0 for ( i = 0 ; i ###Input: - First line will contain $T$, number of testcases. Then the testcases follow. - Each testcase contains of a two
