[D. Xor Sum](https://atcoder.jp/contests/abc050/tasks/arc066_b)↵
↵
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!
