As a tester I can say that problems are great and you should try reading and solving all problems during the contest.

Happy Coding !!

    Codechef takes some time to move the problems to practice. After that it's possible to submit and upsolve the problems. It generally takes 1 day from the day of contest. Hope you enjoy upsolving!
