Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

Understanding scientific notation
Let's consider one case: 2.9979e8
- take the number before "E/e/10" -> 2.9979
- take the number after "E/e/10" -> 8
- Calc the "factor" : If number *after* E is +ve, Multiply, else divide 1 by 1 followed by that many number of zeros.
So -> 1 * 1 00 000 000
- Multiply number *before* E by factor -> 2.9979 * ( 1 * 1 00 000 000) -> 299790000
