Alice and Bob are too smart so called coders.They have now figured out how to escape from Plagiarism. Mayank is struggling with with Plagiarism on codeforces now he wants to figure it out if his two friends Alice and Bob have applied the rule to avoid Plagiarism.

They can perform two type of operations.

1. Change the variable names to any other lowercase Latin letters.

2. Insert lot of commented code.

Sample test case:

Alice submission->link

Bob submission->link

Alice submission->link

Bob submission->link

Please Upvote if they followed the rule.

Note-I was wondering why the submission of same problem during contest of both players have not exceeded 10 minutes.
