I am having a contest in 2 days and I didnt realize there would be 1 problem in the IOI format.

I only have experience with solving problems through stdin and stdout, but I dont know how to solve IOI problems or test my code with the given materials in the .zip files. I have tried looking for tutorials but nothing really came up.

Can someone please provide any useful resources and tutorials for me to cram up before tomorrow? Really appreciate your help
