How to Use Javascript in Hackerrank and Hackerearth?

Question

Can anyone help me how I can able to get the inputs and outputs in Hackerrank and Hackerearth with an example using a JavaScript?

function processData(input) {

//Enter your code here

} 

process.stdin.resume();

process.stdin.setEncoding("ascii");

_input = "";

process.stdin.on("data", function (input) {

  _input += input;

});

process.stdin.on("end", function () {

  processData(_input);

});

Answer 1

You need to do something like this for the solution:

function main(input) {

    //Enter your code here

    var num = parseInt(input, 10);//This line expects input to be a string so convert to an int as per problem

    var res=1;

    for(var i=num;i>1;i--) {

        res *= i; 

    }

    process.stdout.write(res);//This is how you write output.

} 

I hope this will help.
