insertion sort pseudocode

Title:sort a linked list using insertion Sort.idea: The topic requires that we use the insertion sort to achieve the list sort. We build a list of currently ordered lists, and then maintain a variable that points to the next node in the list. Use the variable cur to represent the node that is currently being inserted,

Basic ideasInsert a record into the sorted ordered table to get a new, sequential table with a 1 increase in the number of records. That is, the 1th record of the sequence is considered an ordered subsequence, and then inserted from the 2nd record one after the other until the entire sequence is ordered. If you encounter an element equal to the insert, the insertion element places the element you want to insert behind the equal element. Therefore, the

ObjectiveImagine a reality scene, a few people playing poker, in the process of taking the card, assuming that the number of cards in accordance with the size of the cards, assuming that the hands have a number of cards (in accordance with the size of the cards in order), then the next time we receive the card, we will have just received the card into the hands of the cards in the In reality, this "card" mentality is what we are going to say today, "inserting ideas"Direct

The basic idea of a direct insert sort (insertion sort) is:Each time a record is sorted, the size of its keyword is inserted into the appropriate position in the previously ordered subsequence until all records have been inserted.Set the array to a[0...n-1]:1. Initially, a[0] self into 1 ordered areas, unordered area is a[1..n-1]. Make I=12. Merge A[i] into an or

That is, the 1th record of the sequence is first considered as an ordered subsequence, and then inserted from the 2nd record, until the entire seque
