hello friends i like all of u to suggest me some problem on codechef which can help me in undersatanding graphs,string,trees in a better manner so that by solving those problem i can grow up my command of solving problems related to these datastructures i am beginner and want to implement some of the learnt concept like shortest path problems , number of possible possible ,minimum cost problem etc…

help will be greatly appreciated…

so post the problem code will try them…

Start from the last problem of the page. Solve 2-3 problems per day. If you get stuck, keep racking your brains to find a solution/corner case.

You can also mix it by solving 2 easy + 1 medium problem per day.

thanx for ur suggestion swas_99 but i have already solved some from that section now i want to solve problem related to those that i havve explained above…

It would have been nicer if actual number of submissions made during the contest were also shown in practice section. It will give a better idea of difficulty of problem.
