Preguntas de entrevista para el puesto de Senior Software Developer en Walmart

Standard leetcode question. Interviewer was actually rude and adding comments like "this is wrong" and being overly negative for a code screen. I think the interviewers need to be trained on demeanor and providing a good interviewer manner and politeness. There isn't really a reason to berate someone who couldn't figure out a leetcode question while they are still working through it.
