Coding Exercises

The goal of this repository is to hold a set of exercises for those who want to improve their coding practice. Each exercise will be fully self contained and contain a set of instructions to guide the reader through the proper set of steps required to perform the exercise properly.

Steps to Start

1. Clone this repository using git clone
2. In each exercise folder, there will be a document named Readme.md which you can follow to perform the exercises
3. Follow along with the steps. You can check your answer against the published solutions. Solutions will always be in the solutions folder.

Note In general, exercises are designed to build on each other and skills gained in earlier exercises will be needed in later ones so it is recommended to proceed in order whenever possible.
