Accuracy of programming challenges


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?

We always recommend solving problems incrementally. In other words, you should choose a problem with the appropriate complexity for your current skills. After that, you should work hard until the solution is accepted (1) without working in any other challenge (uploading the solution should be your second “challenge”). Finally, increase the complexity of the challenges that you are trying to solve.
