The problem in question is DECSTR. My solution gives a memory usage of 2.2M. In order to find out how to reduce the mem usage to 1.6M, I looked into some other top solutions but found them almost similar to mine. I then submitted another user’s solution (user-name : thechamp) and got a Mem usage of 2.2M. Codechef still lists thechamps’s solution with a Mem usage of 1.6M. Has there been a compiler upgradation or am I missing something obvious?
