Rishika and Special Number

CodeChefOpen on judge ↗

Rishika loves the number $2020$, she tries to find $2020$ in each and every sequence she is given but unfortunately, she is now tired of looking at all these sequences, your job is to code a program that outputs "YES" if a contiguous subsequence can be removed from the sequence and $2020$ can be made or "NO" if it's not possible **NOTE:** -the array is an **0-based indexed array** ### Input
