It depends on your current level. Try out difficult section on codechef and div1 problems in codeforces.

I think the most tricky…

1.BASE

2.KIRLAB.

HackerEarth, Topcoder and other Competitive Programming sites are welcomed too.

@pratik_gadhiya but still it would be nice if the problems are suggested from Best coders or the problems which are really tricky.


#6

Check out this profiles on codechef for challanging problems solved by them. This would help you out.
