My code is working perfectly for the given test cases but failing for the hidden test cases.Please help!.
Its not possible! Codechef does not provide test cases to users and they are kept hidden intentionally. But there are some online judges like codeforces and atcoder in which test cases are not hidden from the users.
The purpose of why codechef is hiding the test cases is to develop the debugging skills of a user which is very essential for a programmer. When you are stuck with some subtasks or test cases, you have to debug it yourself.
