So im making a website in ASP.NET that creates tests for coding questions and need to test plagiarized inputs, i've made a good one for c# but i still need one for Java and CPP and couldn't manage to do so for a while. Can you reccomend any lib or something i can use for other languages? Mostly to tokenize the code. I've also tried using ANTLR4 but i couldn't figure it much.
