Given a sequence A_1...n of distinct integers, you need to answer whether there exist four indices x,y,z,w such that 1≤x<y<z<w≤n and A_x⊕A_y⊕A_z⊕A_w=0.
Recall that x⊕y means the bitwise exclusive-or between x and y, sometimes expressed as xxory.
The first line contains a single integer n (4≤n≤105).
The second line contains n integers A_1...n (0≤A_i≤105). It is guaranteed that all A_i are distinct.
Output "Yes" if there are four indices satisfying the conditions, or "No" otherwise.
