A transpose of a matrix is simply a flipped version of the original matrix.
We can transpose a matrix by switching its rows with its columns

矩陣的轉置只是原始矩陣的翻轉形式。
我們可以通過切換矩陣的行和列來轉置矩陣

Given a matrix, we have to find its transpose matrix.

給定一個矩陣，我們必須找到它的轉置矩陣。

Example:

例：

Input:matrix:[2, 3, 4, 5, 6][7, 8, 9, 0, 9]Output:Transpose Matrix :[2, 7][3, 8][4, 9][5, 0][6, 9]

在Kotlin中尋找矩陣轉置的程序 (Program to find transpose of 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: Int//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) }val transposeMatrix = Array(column) {IntArray(rows)}//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][$j]: ")matrixA[i][j]=scanner.nextInt()}}//print Matrix Aprintln("Matrix A : ")for(i in matrixA.indices){println("${matrixA[i].contentToString()} ")}//Transpose of Matrixfor(i in transposeMatrix.indices){for(j in transposeMatrix[i].indices){transposeMatrix[i][j]=matrixA[j][i]}}//print Transpose Matrixprintln("Transpose Matrix : ")for(i in transposeMatrix.indices){println("${transposeMatrix[i].contentToString()} ")} }
