Had my phone screen today. Asked 2 LC Medium/Easy:
1. [Leetcode 270](https://leetcode.com/problems/closest-binary-search-tree-value/description/?envType=problem-list-v2&envId=binary-search-tree): Can return either smaller or larger
2. [Leetcode 31](https://leetcode.com/problems/next-permutation?envType=company&envId=facebook&favoriteSlug=facebook-three-months): Was given an integer (ex. 3122641) instead of a list. Convert num to list of digits, and proceed as same.

Interviewer wanted explanation, TC&SC before coding, dry run with examples+ edge cases after.
