MergeSort

MergeSort. Source: Gibbs & Tamassia. MergeSort. MergeSort is a divide and conquer method of sorting. MergeSort Algorithm. MergeSort is a recursive sorting procedure that uses at most O(n lg(n)) comparisons. To sort an array of n elements, we perform the following steps in sequence:

a list = a Linear Recursive Structure (LRS or LRStruct)

a list = a Linear Recursive Structure (LRS or LRStruct). What is a list? the empty list is a list a pair whose tail is a list is itself a list This is a recursive definition! (1) is called the base case, and (2) is called the recursive case.
