I tried a solution based on dp but I am getting WA: link to my solution: https://codeforces.me/contest/1113/submission/136000085

I got the greedy approach, just want to know if it can be solved using dp and what I am missing in dp.

While solving 230A I came across a failing test case 104218672 1 2 1 0 1 0

This is should result in YES, I think, but the judges say that it is NO. Can someone explain to me why this is NO?
