In terms of time, quick sort and merge sort have advantages over time,But it's not as good as sort, and merge sort is more memory-intensive!$arr = [4,6,1,2,3,89,56,34,56,23,65];/*** Bubble Sort* It repeatedly visits the sequence to sort, compares two elements at a time, and swaps them if their order is wrong.* The work of the sequence of visits is repeated until there is no need to exchange, that is, the sequence has been sorted.*/function BUBBLESORTQ

Initialization of the array 1.3.1 Array initialization overview:Arrays in Java must be initialized before they can be used.Initialize: Allocates the memory space for array elements in arrays and assigns values to each array element.Initialization of the 1.3.2 array 1.3.2.1 dynamic initialization: Only the array length is specified when initializing, and the initial value is assigned by the system arraysFormat: data type [] Array name = new data type [array length];The length of the array is act

attention. When the length property is set to a larger size, the state of the entire array does not change in fact, only the length property becomes larger, and when the length property is set earlier than the previous hour, the index in the original array is greater than orThe value of the element equal to length is all lost. Here is an example that shows changing the length property:var arr=[12,23,5,3,25,98,76,54,56,76];Defines an array that contai

to see the differences between Bubble sorting and selection of sorting performance. When N is small, it cannot be seen when it is about several hundred. When N is large, for example, n = 1000 or N = 10000, the Recursive Implementation of Fast sorting will be stuck there, and no results will be produced. The specific code is as follows: /*** Comparison of common sorting algorithms*/# Include # Include # Include # Include # Define N 10# Define demo 1 Void bubblesort (INT

Finding the largest sub-array in an array is a classic question ,《AlgorithmIn the introduction, there is a classic solution for divide and conquer, and time complexity can be O (nlgn ). This issue is discussed in the beauty of programming and the pearl of programming. One of the dynamic planning practices is very delicate, the idea is very good, and the time complexity is optimized to O (n ). The two solutions mentioned above are very enlightening in terms of the division and Control Law and

Today, we summarize the algorithm of simple sorting"Custom Sort"Look for a minimum number, then the number and then the other numbers in the array, if you find that the number is smaller than the number of the two number to swap positions, and then continue to find the next smallest number for the next round of comparisonvar arr = [31,6,19,8,2,3];function Findmin (Start,arr) {var imin =
