kotlin鍵值對數組

Given an array and an element, we have to check whether array contains the given element or not.

給定一個數組和一個元素，我們必須檢查數組是否包含給定的元素。

Example:

例：

Input:arr = [34, 56, 7, 8, 21, 0, -6]element to check: 21Output:21 found at 4 index

程序檢查數組是否在Kotlin中包含給定值 (Program to check if an array contains a given value in Kotlin)

package com.includehelpimport java.util.*//Main Function entry Point of Program fun main(args: Array<String>) {//Input Streamval scanner = Scanner(System.`in`)//Input Array Sizeprint("Enter number of elements in the array: ")val size = scanner.nextInt()//Create Integer array of Given sizeval intArray = IntArray(size)//Input array elementsprintln("Enter Arrays Elements:")for (i in intArray.indices) {print("intArray[$i] : ")intArray[i] = scanner.nextInt()}//Print All Array Elementsprintln("Array : ${intArray.contentToString()} ")//input integer no to be find in arrayprint("Enter Integer Number to be Searched in Array : ")val num = scanner.nextInt()var isFound= falsevar itemAt = 0//Search Given number into Arrayfor(item in intArray){if(item==num){isFound=trueitemAt =intArray.indexOf(item)break}}//Alternatively we can also use contains(num) method of Arrays Class //in kotlin to find specific elements Array or not//var isFound = intArray.contains(num)if(isFound){println("$num found in Arrays at Index $itemAt")}else{System.err.println("$num Not found in Arrays !!")} }

Run 1: ----- Enter number of elements in the array: 7 Enter Arrays Elements: intArray[0] : 34 intArray[1] : 56 intArray[2] : 7 intArray[3] : 8 intArray[4] : 21 intArray[5] : 0 intArray[6] : -6 Array : [34, 56, 7, 8, 21, 0, -6] Enter Integer Number to be Searched in Array : 21 21 found in Arrays at Index 4 -------- Run 2: ---- Enter number of elements in the array: 7 Enter Arrays Elements: intArray[0] : 3 intArray[1] : 4 intArray[2] : 5 intArray[3] : 7 intArray[4] : 90 intArray[5] : -89 intArray[6] : 5 Array : [3, 4, 5, 7, 90, -89, 5] Enter Integer Number to be Searched in Array : 345 345 Not found in Arrays !!
