I haven’t implemented data structures as of now on any of the codechef problems. can someone suggest me some questions that are available on codechef that are based on data structure i.e trees,undirected graphs,directed graphs,path matrix,shortest path algorithms…?
The difficult of problems should be from Easy->Medium as such.
http://www.codechef.com/problems/TWSTR is an easy problem. I coded XYZ data structure for this problem, for the first time in my life. Its better if you discover XYZ yourself;)
@vinayak grag the problem you mentioned http://www.codechef.com/problems/TWSTR can be done using arrays…I couldn’t figure out which data structure you are talking about…can u pls help???
