can someone provide me with some codechef problems from practice section from which i can learn the use of hashmap clearly…

P.S. i’m new to STLs.

Thanks in advance.

Hello,

There are 2 very specific data structure problems which train exactly the data structure you have required!!

They are in practice section and were used during some of later contests of 2012.

Here they are:

Also, from the most recent initiative, Codechef for Schools there is also the very nice problem:

Please note that the last problem involves some extra mathematics besides using only maps and it also relies on the use of sets, but, it’s also a very good problem

Good luck,

Bruno

thanks…

You are welcome!
