Test data for zco, inoi and ioitc questions

Can somebody provide me the links from where I can get the test data to past ZCO, INOI and IOITC questions?

Okay … I have found something … i have found theoretical solutions and problems from past contests from 2002 -2015 .

http://www.iarcs.org.in/inoi/2015/

http://www.iarcs.org.in/inoi/2014/

.

http://www.iarcs.org.in/inoi/year/ (replace year by 2002 to 2015)

Also , go at bottom of page and look , there u will find the questions and solutions.

Hope that helps.

But these sites contains question papers only, no solutions (Except for first few years)

This page contains the problem statements and the test data for some problems - http://www.iarcs.org.in/inoi/contests/allproblems.php
