Merge and sort (C #)   There are many algorithms that are recursive in structure: To solve a given problem, the algorithm needs to call itself one or more times to solve the relevant subproblems. these algorithms usually adopt the Grouping Strategy:

Bubble sort (C #) The sorted record array R [1. N] is vertically arranged. Each record R [I] is considered as a bubble with the weight of R [I]. Key. According to the principle that a Light Bubble cannot be under a heavy bubble, scan the array R

Heap sorting (C #) The heap data structure is an array object, which can be regarded as a Complete Binary Tree. Complete Binary Tree) If the height of a binary tree is set to H, except for layer H, the other layers (1 ~ H-1) are all reached the
