Q1. Implement cd. Given current working directory and argument move to final path E.g. cwd - /a/b/c arg - d Output - /a/b/c/d
Missed one case while explaining the solution. Interviewer corrected me. Interviewer while coding pointed out a case where solution wont work I was quickly able to understand why. Used stack
