ordered list: sorted by key value. When you delete the chain header, delete the minimum (/maximum) value, and when you insert it, search for the insertion position. when inserting, you need to compare O (N), average O (n/2), delete the minimum (/maximum) of the data in the chain with the efficiency of O (1), If an application requires frequent access (insert/Find/delete) minimum (/maximum) data items, then ordered linked list is a good choice Priority queues can use an ordered list of linke
