Winning Sequence

CodeChefOpen on judge ↗

Consider a sequence of non- negative integers b(1), b(2) … , b(n) of length n. The given sequence is called a winning sequence if and only if there exists integers p and q between 1 and n (both inclusive) such that a(p) xor a(p+1) xor a(p+2) …. xor a(q) = 0. The xor operation is the bitwise xor operation between two integers. The task at hand for you is to compute the number of sequence made of n
