please provide me with some test cases an dtheir answers
Sorry Buddy ongoing Competition !
you can ask…after the contest ends…
Please read codechef guidelines, you cannot ask question related to on-going contest.
Try making your own random cases or make a program to generate random testcases.
a better idea is that if u have got some points atleast with some brute forcing, use testcases from that program and use them for testing ur new algorithm of your new program. this idea is very useful.
