kotlin 查找id

Given a matrix, we have to find frequencies of even and odd numbers.

給定一個矩陣，我們必須找到偶數(shù)和奇數(shù)的頻率。

Example:

例：

Input:matrix:[4, 5][6, 0][9, 2]Output:Even Elements Frequency : 4Odd Elements Frequency : 2

在Kotlin中尋找矩陣中偶數(shù)和奇數(shù)頻率的程序 (Program to find frequencies of even and odd numbers in a matrix in Kotlin)

package com.includehelpimport java.util.*// Main function, Entry Point of Program fun main(args: Array<String>) {//variable of rows and colval rows: Intval column: Intvar oddCount = 0var evenCount = 0//Input Streamval scanner = Scanner(System.`in`)//Input no of rows and columnprint("Enter the number of rows and columns of matrix : ")rows = scanner.nextInt()column = scanner.nextInt()//Create Arrayval matrixA = Array(rows) { IntArray(column) }//Input Matrixprintln("Enter the Elements of First Matrix ($rows X $column} ): ")for(i in matrixA.indices){for(j in matrixA[i].indices){print("matrixA[$i][$j]: ")matrixA[i][j]=scanner.nextInt()//count Odd and Even elements Frequencyif(matrixA[i][j]%2==0) evenCount++ else oddCount++}}//print Matrix Aprintln("Matrix A : ")for(i in matrixA.indices){println("${matrixA[i].contentToString()} ")}//Print Frequencyprintln("Even Elements Frequency : $evenCount")println("Odd Elements Frequency : $oddCount") }
