quicksort algorithm with example in data structure

1. Give a new name to an already existing type, thus creating a new type: typedef oldtype Newtpye;2, Emum Color{red,orange,yellow,green,blue}; where Color is called an enumeration type, {} is called an enumeration constantBy default, the associative integers of enumerated constants start with 0, this example is 0~4, or can be set toEmum color{red = 1,orange,yellow,green,blue}; The associated numbers of the new examples are the ";Emum color{red = 2,ora

for the and of all sub-arrays. Requires a time complexity of O (n).For example, the input array is 1,-2, 3, 10,-4, 7, 2,-5, and the largest sub-array is 3, 10,-4, 7, 2, so the output is the and 18 of that subarray.

The interrelationships between data are called logical structures . Generally divided into four basic structures: Data elements in a collection structure are in addition to one type. There is no other relationship. There is a one-to-one relationship between data elements in a linear

can be reduced to O (n);But the quick order is opposite, when the original table is basically orderly, degenerate is the bubble sort, the time complexity increases to O (N2);The order of the original table has little effect on the time complexity of simple selection, heap sort, merge sort and cardinal order. Second, the sorting algorithm thought summary The following is a summary of their ordering ideas in the order shown above. 1. Insert Directly In

Exchange, for example:1), we have array int[] Arraydata = {5, 9, 6, 7, 4, 1, 2, 3, 8};2), in the first round, we use 5 as the base to sort the left and right, then 5 of the index 0 is the first pit. We need to find a number to fill the pit.3), first right-to-left search. OK, we found 3, which is index 7. Let's write 3 to Arraydata[0] (2 dug in the pit yo). Then arraydata[7] is the pit to be filled.4), and then search from left to right, at which poin
