I tried solving the ‘Chef & Integers’ question in the September Challenge. But, in the sample input, they have not written anything about the number of test cases. I assumed that there would be just one test case, but I am getting a TLE. I tried optimizing it but it did not work. Yes, my algorithm may be poor, but why does this question not contain this trivial information? Any tricks here?
Input format is described well. Your assumption that there is just one test is correct, because if there is not written about multiple test cases there are only those inputs described in input section.
