1. Simple Sorting Problem where you're asked to sort a given array of integers, first by frequency of the numbers and then by the order of the element in the array.
2. Return a list of all string permutations with vowels ['a', 'e', 'i', 'o', 'u'] for a given length n. There were some additional constraints on the ordering of the allowed strings.
3. Photo Album Problem: https://leetcode.com/discuss/interview-question/424737/photo-album-problem

I worked through Q1 and Q3 first. Unfortunately, I ran out of time and couldn't pass all test cases for Question 2. Received a rejection email later that day.

Good luck!
