Java programmers must know eight major sorting orders, and java programmers must know
1. Insert directly to sort(1) Basic Ideas:In the number of groups to be sorted, assume that the number of the preceding (n-1) [n> = 2] is alreadyNow we need to insert the nth number into the previous ordered number so that the n numberIt is also sorted. This repeats until all the rows are sorted.(2) Instances3) implemented in java2. Hill sorting (minimum incremental
There is a hidden danger in VIP orders of chengtong Network Disk (400gb.com). One-click VIP activation + System Administrator (but it seems that there is no permission)When you make a payment for the VIP service, the City Network Disk uses a relatively safe order id for payment, which is relatively safer than the amount directly used for transmission.
However, for the Order id, like most manufacturers, it uses simple 1, 2, 3, 4 ,......, n-1, n format.

Based on the above analysis, we would like to change the process a little bit, that is, the order has been created before payment, so even if the payment can not be from the third-party payment site to return, we will not have the user payment success in the background without orders. The revised blueprint is basically the following:

Problem descriptionbobo has a sequence A1, A2 ,..., An. He is allowed to swap two
AdjacentNumbers
Give us a sequence and let us calculate its number in reverse order:
For example, 3 2 1 4
Number of reverse orders: 2 + 1 + 0 + 0 = 3
In this way, we define the reverse number of a sequence: sequence A1 A2 A3 A2...
The number C in the descending order of this sequence is equal to the sum of the numbers in the descending order of A1, a2..., that is, c = sum (CI)
CI is the total number of numbers that meet AI> AJ (j> I), that is, CI = sum (AI> AJ) (j>

Insert sort directly(StraightInsertion Sort) is the simplest sorting method. Its basic operation is to insert a record into an ordered table with sorted orders, in this way, a new ordered table with 1 Increase in the number of records is obtained. Time Complexity:O (N ^ 2).Understanding: Insert each record to be sorted into a proper position of the ordered sequence in sequence. The insert position is compared with each element of the ordered sequence
