This is the problem

These are the two solutions : (correct one) (wrong one)

The one line change is during input taking iteration where I am assigning value to dp[a[i]]. first I assigned dp[a[i]] = 1 , which gave wrong answer at large input(so can't debug by myself) but then when I changed it to dp[a[i]] = 0 , it made the solution accepted , but if you will see just next interation after the input taking iteration , it doesn't make sense to me because dp[a[i]] = max(dp[a[i]] , dp[a[i] — 1] + 1) should take care of the dp[a[i]] = 1. I don't know am I missing something?
