Programming Challenges Solution Repository

Includes solutions for uWaterloo's CCC, Hackerrank, GeeksForGeeks, LeetCode, Google Kickstart, and some useful graph algorithms in python 3.

NOTE: I made this so that others may learn from the techniques I have used to solve problems that may or may not be mainstream. An example of this is 2012 S4. The solution found online for Python3 is made by 4/5 people, uses a technique as if they were programming in C++, and barely passed the test cases (in terms of time). I had first created a solution that couldn't pass on time, but only because I had never used the set data structure in Python. As soon as I changed the algorithm to use a set instead of a list, my solution became more efficient than the existing online Python3 solution. I now use sets a lot and always look for this easy optimization.

Another note: I've also noticed that there is a lack of organization / design / aesthetic when it comes to programmers sharing their solutions, and so this repository aims fill that void. I'm obviously not the smartest programmer and I like to create projects so this repository might not have everything you look for.
