RWC #394 @cassidoo.co gist: gist.github.com/sreetamdas/5... Feel like there's a better way of doing this, but I've def gotten a bit rusty with my Elixir 😅

Solution to Rendezvous with Cassidoo #394, problem statement:

A store is going out of business and will reduce the price of all products by 10% every week leading up to the closing date. Given the closingDate, visitDate, and the originalPrice of a product, write a function that returns the price of the product on the visitDate. You can assume that originalPrice is a positive number.

RWC #390 @cassidoo.co gist.github.com/sreetamdas/5... Haven't felt "dirty" while writing code for some time now 😅

Solution to RWC #390 in Elixir, problem:

Write a function that evaluates a postfix expression (also known as Reverse Polish Notation) and returns the result. The expression will contain single-digit integers and the operators +, -, *, and /. You can assume the input is always a valid expression!

Examples:

evaluatePostfix('12+')
> 3

evaluatePostfix('56+7*')
> 77
