Amazon SDE intern interview questions

They were online assessments for coding.

for the first part, it was pretty straightforward, a code was given and instead of adding the correct thing, it added something else to answer so just needed to fix small things like that. In the second part, I got 2 questions and the first one is finding pairs of closed parenthesis, so if ()() this was given then return 2 if there are unclosed ones return -1. The second question is to find the largest square when a matrix of 0and 1 are given.
