The leetcode web coding IDE has a premium debugger feature – however this is not enabled during the contest. Recently I found out that you can actually print to STDOUT and then when you run your solution – you will see the output – this is an easy yet powerful method to debug when you don’t have other better solutions.

This is a great way to debug your code when you don’t have a IDE at hand – sometimes I participated the weekly contests on iPad where I don’t have IDE and I don’t have access to the inbuilt leetcode debugger as well – in this case, the printing to stdout is the only practical way of debugging printing the variables. Prior to this, I can only change the code and return the variable as a debugging technique – which is very inefficient.
