Given a matrix, we have to print its lower triangular.

给定矩阵，我们必须打印其下部三角形。

Example:

例：

Input:    matrix:    [2, 3, 5]    [6, 7, 8]    [9, 2, 1]    Output:    [2, 0, 0]    [6, 7, 0]    [9, 2, 1]

程序在Kotlin中打印矩阵的下三角 (Program to print lower triangular of a matrix in Kotlin)

package com.includehelpimport java.util.*// Main function, Entry Point of Programfun main(args: Array
    
     ) {    //variable of rows and col    val rows: Int    val column: Int    //Input Stream    val scanner = Scanner(System.`in`)    //Input no of rows and column    print("Enter the number of rows and columns of matrix : ")    rows   = scanner.nextInt()    column = scanner.nextInt()    if(rows!=column) {        println("Matrix should be Square matrix , Rows and Col size must be Same !!")        return    }    //Create Array    val matrixA     = Array(rows) { IntArray(column) }    //Input Matrix    println("Enter the Elements of First Matrix ($rows X $column} ): ")    for(i in matrixA.indices){        for(j in matrixA[i].indices){            print("matrixA[$i][$j]: ")            matrixA[i][j]=scanner.nextInt()        }    }    //print Matrix A    println("Matrix A : ")    for(i in matrixA.indices){        println("${matrixA[i].contentToString()} ")    }    //get lower triangular of matrix    for(i in matrixA.indices){        for(j in matrixA[i].indices){            if(j>i) matrixA[i][j]=0        }    }    //print Matrix A    println("Lower Triangular of Matrix : ")    for(i in matrixA.indices){        println("${matrixA[i].contentToString()} ")    }}
