uDebug Tool by Robbinb1993 provides an editor that lets users input their code and have it compiled from a list of several languages. They are then able to search for any competitive programming problem supported by uDebug and provide input for this problem. This is done by either using input from the input table or by inserting custom input. The output of the user code and the one from uDebug are then processed compared to one other making it straightforward for the user to spot the differences, if any. The Random Input Generator (RIG) feature allows users to generate random inputs on which their code will be tested.
