I just found that one of the question of **COMB2018** https://www.codechef.com/COMB2018/problems/COMB7 is copied directly from a HackerEarth past contest https://www.hackerearth.com/practice/algorithms/string-algorithm/basics-of-string-manipulation/practice-problems/algorithm/swapping-game-6/ .

Those who haven’t even submitted simple digit DP problem have also submitted this.

Cheers to ABV-IIITM Gwalior for selecting participants for onsite for a prize money of 75k on the basis of this ranklist.

Please consider the rank list removing the above mentioned question copied from other platform since their solutions are easily available.
