insertion sort pseudocode

Direct Insert Sort The idea of a direct insertion sort is easy to understand and it is like this:1. The sorted array is divided into sorted and unsorted parts, and the first element is considered to be in order at the beginning.2. Starting with the second element, find the appropriate location for the element in the sorted array and insert the location.3. Repeat

1. Insert SortThe Insert sort (insertion sort) is a simple and intuitive sort algorithm. It works by building an ordered sequence, scanning the sorted sequence for unsorted data, and finding the location and inserting it. Insert sorting on implementation, usually using in-place sorting (that is, just use the extra spac

Number of array elements: NAlgorithm idea: Divided into a set of ordered groups and a group of unordered groups, each in order from the unordered group to take a comparison with the front, if less than the former exchange, otherwise break; until the last unordered element is compared, the first order group is an array of elements, and the remainder is unordered.The code is as follows:PHP$arr=Array(232,3,44,234,456,3432,289); functionInsertsort ($arr) { for($i= 1;$iCount($arr);$i++)

The basic idea of inserting a sort (insertion sort) is to insert a record to be sorted each time, by its keyword size, into the appropriate location in the previously ordered sub-file until all records are inserted.basic ideas and pseudo-codeAfter j-1 the processing, a[1..j-1] has been in good order. J-Pass processing only a[j] into the appropriate position of l[

The insertion sort is a sort algorithm that does not change the original sequence (array), but instead creates a new sequence that operates on the new sequence. Here is a small to large sorting as an example to explain. Basic ideas and illustrative examples The basic idea of inserting a sort is to add elements one b

The basic idea of a direct insert sort (Insertion sort) is to insert a record to be sorted each time, by its keyword size, into the appropriate position in the previously ordered subsequence until all the records have been inserted.set the array to a[0...n-1]. 1. initial time. A[0] self into 1 ordered areas, unordered area is a[1..n-1]. Make I=12. merge A[i] int

The shell sorting algorithm was first proposed by the D.L shell in 1959, assuming that the elements to be sorted have n, then each insertion sort is not the same as the elements, but goes to an interval. The shell first sets the interval to N/2, then jump to the insertion sort, and then set the interval to N/4, jump t

Sort a linked list using insertion sort.Hide TagsLinked List SortAnalysis: The chain list is divided into two parts: ordered and sorted, the order of the null end, cur inserted between preinsertion and insertion, next save Cur->next. Also, note that the use of dummy simplifies the insertion of head nodes.Time complexit

; } } if(flag) { Break; } } }According to the above bubbling implementation, the Wakahara array itself is ordered (this is the best case), only need to n-1 the comparison can be completed; In reverse order, The number of comparisons is n-1+n-2+ ... +1=n (n-1)/2, the number of exchanges and the number of comparisons are equivalent. Therefore, its time complexity is still O (n2). Overall, the bubble sort performance is st

1. Some concepts in sorting(1) Algorithmic Stability: if there are two elements a and b in the sequence to be sorted, the corresponding keywords key_a and key_b are equal, and a precedes B in the original sequence. If a sort algorithm is used, a is still in front of B, then the algorithm is called stable, otherwise it is called unstable. It is worth noting that the stability of the ranking algorithm does not measure the merits and demerits of an algor
