- Given a collection of Russian dolls, if one doll is smaller than another, it can fit inside the larger one. If dolls are of equal size neither can be placed inside the other. Imagine the number of dolls is given to you in an array such that each number in the array is representative of the size of the doll. Return the total number of dolls left after you have placed all possible smaller ones inside any larger ones. i.e.
- [2,2,3,3] returns 2 dolls because each 2 can fit inside a 3
- [1,2,2,3,4,5] returns 2 dolls because 1, one of the 2s, 3, and 4 can all fit inside of 5, leaving just 2 and 5.
- Given a list of items that each have a category and value, create a function that outputs each category with it's corresponding values sorted in alphabetical order. i.e.
