 1 | This my personal list of recommended problems to do for interview preparation. 
 2 | Aim to be able to do mediums in < 30 mins.

 4 | - A problem often has valid approaches other than the category it's under. 
 5 | - The fact there is a category at all is often a large hint that you would not normally have.
