1942. The Number of the Smallest Unoccupied Chair

Quite a fun problem! Really good one to practice your heaps.

2028. Find Missing Observations

Pretty easy math problem, easy implementation as well. (1942. was much harder)

2191. Sort the Jumbled Numbers

Concepts: Array, Sorting

This was my 100th Medium question, LFG! Two different solutions, I used the one that optimizes for time complexity with N Log N, but make sure to think about both.

This was my first hard problem, took me a while to code up, but managed to solve it!

Took a while to solve again, and implementation was quite badly written, but still happy to have solved it.
