We only suggest our users to participate in the challenges from laptop/desktop. In order to solve linked list-based questions, a good knowledge of recursion is important, because a linked list is a recursive data structure. For each problem, based on the specifications mentioned in the problem statement, there will be one or more input files and corresponding (correct) output files. Any large arrays should be declared globally, outside of any functions - putting an array of 100000 ints inside a function probably will not work. It is recommended that you ensure that your system meets HackerEarth's compatibility requirements and check your Internet connection before starting the test. The head pointer given may be null meaning that the initial list is empty. Ensure that your program conforms with the output format that is required.

It is recommended that you attempt the test in an incognito or private window so that any extensions installed do not interfere with the test environment. Please note that we will remove this constraint very soon. Solve Challenge. It was conducted on Hackerearth of time limit 1 hour and 30 minutes. Hence, Total execution time <= (Time Limit * Number of input files). If you take one node from a linked list, the remaining data structure is still a linked list, and because of that, many linked list problems have simpler recursive solutions than iterative ones.
