I’m solving the first 3 programming challenges for the technical challenge stage. But I’m stuck at one challenge from codeforces with a difficulty of 1000.
My code executes some test cases with success and then it fails when it finds a particular test case because of the complexity. I fix the code but eventually another issue is found.
So do I have to pass all of the test cases from codeforces? or is it a better idea to try another challenge or website?
