Answer 1

Try this: actually this a problem from codeeval.com

I solved it in this way .

This program takes a file as the argument so i used a little node js to read the file.

Here is my code.

var fs  = require("fs");
fs.readFileSync(process.argv[2]).toString().split('\n').forEach(function (line) {
    if (line !== "") {
        var arr = line.split(" ");
        var arr1 = arr[0].split(":");
        var arr2 = arr[1].split(":");
        var time1 = parseInt(arr1[0])*3600 + parseInt(arr1[1])*60 + parseInt(arr1[2]);
        var time2 = parseInt(arr2[0])*3600 + parseInt(arr2[1])*60 + parseInt(arr2[2]);
        var dif = Math.max(time1,time2) - Math.min(time1,time2);
        var ans = [];
        ans[0] = Math.floor(dif/3600);
        if(ans[0]<10){ans[0] = "0"+ans[0]}
        dif = dif%3600;
        ans[1] = Math.floor(dif/60);
        if(ans[1]<10){ans[1] = "0"+ans[1]}
        ans[2] = dif%60;
        if(ans[2]<10){ans[2] = "0"+ans[2]}
        console.log(ans.join(":"));
    }
});
