Changes 9/19/14

Java:

• Finished up the eimacs hash table section
• I feel like it wrapped up too quick, it just showed the basics without really talking about advanced hash collision strategies and stuff like that
• Started looking at sorting algorithms
• It's walking me through how an in-place quicksort works, which is when an array is sorted just by swapping the placement of elements
• It's very complicated, but they do a good job of walking you through it slowly
• They have an interactive example where it highlights the step the program is on, and explains what is being done
