Java Data Structures and algorithms (2)-Sort (bubble, insert, and select Sort)

Sorting needs to be mastered by having a bubbling sort, inserting sort and selecting sort.Bubble sort: The outer loop goes from back to front, the memory loops from the back to the outer loop, the adjacent array item 22 compares, and the larger value is moved back.Insert sort: Starts at the middle of the

Bubble sort and simple selection sort--java implementation

1. Bubble sort1) Principle: iterate over the sequence to be sorted, a comparison of two elements at a time, assuming they are in the wrong order to exchange them. The work of visiting the series is repeated until there is no need to exchange, that is to say, the sequence is sorted out. 2) Code implementation:Package Com.test.sort;public class bubblesort{public static void sort (int[] data) {for

significantly lower than the element interchange) The index of the variable representing the minimum value is then compared to the index of the starting element, and if it is not the same, the starting element is interchanged with the minimum element (so that the order is completed by a smaller number of interchange cycles).1 for(inti = 0; i ) {2 intindex =i;3 intValue =Arr[i];4 //If there is a better element than the starting element value, assign t

Java bubble sort and direct selection sort code essay

Bubble sort: There are many kinds of enshin, some first determine the maximum value put to the back, some first determine the minimum value to the front, there is the reverse, first determine the minimum value of the position, but the essence is: constantly 22 comparison, exchange position ... The first trip to determine a maximum (minimum) value placed in front (behind), the second trip, the exclusion of t

of comparisons, and the 11th line for loop controls the number of I (minimum or maximum) and the remaining number of comparisons2. Bubble sortThe principle is that the adjacent number 22 is compared, in order from small to large or from large to small to exchange,After such a trip, the largest or smallest number was exchanged to the last,And then start from the beginning to the 22 comparison exchange, until the end of the second placecode example:1

Java bubble Sort and select Sort Sample _java

The basic concept of bubble sort (bubblesort) is to compare the number of adjacent two digits, place the decimal number in the front, and put the large numbers behind. On the first trip: first compare the 1th and 2nd numbers, put the decimal number before the big number put. Then compare the 2nd and 3rd numbers, put the decimal places before the large number, so continue until the last two, the number of de

Java Implementation bubble sort

finished.Third, the realization of ideas:With the double loop, the outer loop variable is set to I and the inner loop variable is set to J. If there are n number needs to be ordered, then the outer loop repeats n-1 times, the inner loop repeats n-1,n-2,...,1 times sequentially. Each comparison of the two elements are related to the inner loop j, they can be identified by a[j] and a[j+1], the value of I sequentially,..., n-1, the value of each i,j is 0,1,2,... n-i.Set the array length to N:1.

of arr[i], the condition in the inner loop is j>i, because Arr[i] is lined up in front of the order. Each time you compare from backward to arr[i] you don't have to go on.Of course, the core code above can also be written in the following form:1Private Static voidBubbleSortTest2 (intarr[]) { 2inttemp = 0; 3 for(inti = arr.length-1; i > 0; i++) { 4 for(intj = 0; J ) { 5if(Arr[j] ]) { 6 temp = arr[j+1]; 7 Arr[j+1] =Arr[j];8 Arr[j] =temp;9 }10 }11 }12}Here the thought is th
