I have read many introductionsJavascriptThe article on object-oriented technology is dizzy. Why? It's not because it's not well written, but because it's too esoteric. The objects in javascript haven't clearly explained what's going on. As soon as

Iterator Pattern Iterator ModeScenario ConjectureIf you write code frequently, you will encounter traversing an array. Use the for loop to obtain the array subscript and perform further operations. For example, the following code: Int [] array = new

Knowledge Points: 1. Fixed-length array New // array of 10 integers, all elements initialized to 0 New // A string array of 10 elements, all elements initialized to null // An array (String) of length 2 is inferred by the compiler, and the initial

/*1. Define a function function that dynamically extracts the maximum value of an element in int[].Class Demo{public static void Main (string[] arge) {int[] array = new int[]{99,6,999,44};System.out.println (Max (array));}public static int Max (int[]

1. Bubble Sorting Method: Compare the adjacent two elements, if the front is larger than the back, swap two elements, a trip down, the largest number on the far right, just like bubbles rise.Code:/** Bubbling*/ Static voidBubble_sort (int[] Array)

Direct insertion sort of sorting algorithmFirst, the process of directly inserting the sort1. The direct insertion sort consists of N-1.2, the basic idea: the first element as an ordered sub-sequence, and then sequentially from the second record

An array is a collection of elements stored in a contiguous block of memory that is used to store multiple data of the same type.Index (subscript): The number of each data in the array, the Int class, starting from 0 to the length-1 number.Array

  Principle:   The algorithm is as follows:       Private function compoud (N: uint, C: uint): void { Var pickIndex: int = 0; Var X: int = 1; Var Y: int = 1; Var P: int = 1; Var I: int = 0; Var arr: Array = new Array (); Var src: Array = new Array
