first of all try to use map also for a[i] = 0 take a variable with initial value as 'a' and increment it and add to ans if a[i]=0 and only check map for a[i] other than 0
How does that make a huge difference? Can you tell me why it was showing TLE at tc3. I appreciate your advice brother. But can you explain me why using map for a[i] = 0 can make a huge difference.
See the blog on Blowing up unordered_map, and how to stop getting hacked on it
just changed ss+=x.first

Man this was the problem. It ruined my whole contest. Thankyou.
