Hack The Rank

A tool that should make it easier to write and test Go solutions for HackerRank challenges. The hacktherank tool allows you to run a set of test data samples against your source code.

Usage

Install the tool

go install github.com/mokiat/hacktherank@latest

Create a test data file

This is a file which contains the input lines to test with and the expected output lines. It is possible to specify multiple test scenarios (or samples) within a single file. Following is an example for a sum challenge.
```
input:
3 5
output:
8
input:
10 20
output:
30
```
Note: Make sure that all relevant new-line symbols are added and that no unexpected blank space characters are inserted. The tool matches lines exactly - without trimming.
Write your solution

You should create a main.go file somwhere and add your Go implementation to it.
Test your solution with the hacktherank tool

Following is a demonstration using the example folder of this project.
```
hacktherank -main example/main.go -data example/data.txt
```
Iterate over your solution

Once you start tackling more complicated challenges, it is unlikely that you will be able to solve them on the first try.

Make adjustments to your main.go file and just rerun the command to see if you have solved it.
