Stdin in javascript/nodejs

[Ratul Jain]

Hey guys I am trying to solve on problem in javascript and I am stuck at taking input from stdin. The question will provide an integer N (number of test cases) followed by N lines. I can't figure out how to take input in this particular way.

I have seen some solutions but those are not working in my case. I can't mimic the same behaviour. It should ask for the N and then run the loop N times that takes input from the user and returns the solution for the particular test case
