How can I add programming challenges to my website with the ace editor and the hackerearth api?

I am unsure how to create programming challenges for my website like the ones on https://coderbyte.com/. My website should be able to test user submissions for many test cases and make sure that their programs produced the correct results. My website will use the Ace editor and the hackerearth api. https://www.hackerearth.com/docs/wiki/developers/v3/. https://ace.c9.io How can I implement all of this? Thank you in advance
