From my HackerRank solutions. operators that evaluate to natural numbers: Check - prime number checker determines if the given number is a prime; Find next - prime number generator finds the smallest prime number greater than the provided number; Find previous - prime … Input Format The first line contains a single integer T, denoting the number of test cases. In the custom checker, you can also choose to give a partial score to a candidate who lists 3 prime and 2 composite numbers. Over the course of the next few (actually many) days, I will be posting the solutions to previous Hacker Rank challenges. In case there is : no prime number, then a blank line should be printed.
