Bubble Sort - Answer -Sorting method where if the n+1 index is greater than n, the two indices are swapped. This is one of the most inefficient sort methods that exist. It's efficiency is O(n^2) in average and worst case scenarios.
Insert Sort - Answer -As sort continues, the newest value is placed into the appropriate spot of whatever has already been sorted. Depending on the scenario, this has good or bad sort times
Selection Sort - Answer -Sorting process where the smallest element is selected from the unsorted array and swapped with the leftmost element, and that element becomes a
part of the sorted array. This process continues moving unsorted array boundary by one
element to the right.
Merge Sort - Answer -Sorting method where an array is broken into smaller and smaller arrays, sorted within the smaller arrays, then the smaller arrays are merged back together.
Interface - Answer -An object type that doesn't have any instance variables or constructors, and is only made up of abstract methods
