[Help] Divide an array into two subsequences such that the xor of their ors is maximum

Правка en2, от cyber_simar, 2024-07-19 14:42:37

Given an array A of length n(n≤105, ai<250), divide it into two subsequences X and Y such that (x1|x2...) ⊕ (y1|y2...) is maximum. Print the maximum OR(X) ⊕ OR(Y).

Any help would be appreciated. Thanks!
