Day 18: Sums of Geometric Series for the Win

Ya Boy did it!!! Figured out how it all worked. Thanks to some amazing YouTube videos and Math Stack exchange I was able to learn what needed to be applied to my theory to prove it is correct for any simple recursive function. In addition to that, I now understand why I got the wrong answer for the problem I was stuck on. Boy, I’m telling you today feels great!

TLDR;

Okay, so here are the highlights of what I did:

  • Still reading through the book “Cracking the Coding Interview” by Gayle Laakmann McDowell. Learned how to apply the formula for calculating the sum of partial geometric series. Shout out to This Post on Math StackExchange and the Organic Chemistry Tutor’s YouTube Videos. They both helped me a ton. Wow what a feeling. I can finally move on. At some point though I need to come back to my notes and properly document them. Currently they are a mess LOL.

Conclusion

That’s all for today. This is my sixth round of the “#100daysofcode” challenge. I will be continuing my work from round five into round six. I am currently working through the book “Cracking the Coding Interview” by Gayle Laakmann McDowell. My goal is to become more familiar with algorithms and data structures. This goal was derived from my goal to better understand operating systems and key programs that I use in the terminal regularly e.g. Git. This goal was in term derived from my desire to better understand the fundamental tools used for coding outside of popular GUIs. This in turn was derived from my desire to be a better back-end developer.

I have no idea if my path is correct but I am walking down this road anyways. Worst case scenario I learn a whole bunch of stuff that will help me out on my own personal projects.
