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/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.
This page contains the problem statements and the test data for some problems - http://www.iarcs.org.in/inoi/contests/allproblems.php
But these sites contains question papers only, no solutions (Except for first few years)
