CANT FIND WHICH INPUT HAS BEEN GIVEN TO THE CODE AND WHAT THE OUTPUT HAS COME IN NOVEMBER CHALLENEG
Provide a link to the specific problem, if your issue is that specific. But, per the rules, nobody should be asking or answering questions on how to solve problems in current ongoing competitions.
On the other hand, if you are (for example) having trouble understanding how to use IDE, which I would recommend at least when starting to use the site, make sure you have checked the “Custom Input” option underneath the code window and provided some sample input data in the dialog box that then becomes visible.
Also, in general, note that the input and output are “bare” - you should not output prompts or descriptors except exactly as indicated by the problem. Typically you will read some very specific sequence of numbers, some on separate lines and some space-separated on a single line, and your output will also just be numbers or some exactly specified words.
The test cases used to evaluate your submissions are kept confidential. You can rely on them conforming to the stated limits in the problem description.
