Atcoder Beginner Contest 50 D.XOR-sum help!!!!
Can someone please help me in this task. I know if, u=a xor b & v=a+b then v=u+2(a&b)
But I have no clue how to proceed beyond this point. The editorial uses a DP solution but I am unable to understand the recurrence relation used. Please help!!
Thanks!
