Hi,

I am having trouble finding out where the code fails for problem http://mirror.codeforces.com/problemset/problem/279/C.

My logic is as follows:-

1. Store the entries in an array till the time the answer is valid
2. Check if the r in the array contains less than or equal to l then the answer is "Yes".
3. My code fails at test case 21.
4. Please point the error in the code.
5. It would be good if you can give a small sample test case where the code fails.

Thanks in advance.
