An **upper triangular matrix** is a matrix in which all the lower triangular elements are zero, or all the elements below the principle diagonal will be zero.

**上三角矩阵**是一个矩阵，其中所有下三角元素均为零，或者所有在主对角线以下的元素均为零。

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

给定一个矩阵，我们必须打印其上三角形。

**Example:**

**例：**

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

### 在Kotlin中打印上三角矩阵的程序 **(**Program to print upper triangular matrix in Kotlin**)** ###

package com.includehelp
    
    import java.util.*
    
    // Main function, Entry Point of Program
    fun main(args: Array<String>) {
    
        //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 Upper 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("Upper Triangular of Matrix : ")
        for(i in matrixA.indices){
            println("${matrixA[i].contentToString()} ")
        }
    }

**Output**

**输出量**

Run 1:
    Enter the number of rows and columns of matrix : 4
    3
    Matrix should be Square matrix , Rows and Col size must be Same
    ---
    Run 2:
    Enter the number of rows and columns of matrix : 3
    3
    Enter the Elements of First Matrix (3 X 3} ):
    matrixA[0][0]: 2
    matrixA[0][1]: 3
    matrixA[0][2]: 4

    matrixA[1][2]: 7
    matrixA[2][0]: 8
    matrixA[2][1]: 9
    matrixA[2][2]: 8
    Matrix A :
    [2, 3, 4]
    [5, 6, 7]
    [8, 9, 8]
    Upper Triangular of Matrix :
    [2, 3, 4]
    [0, 6, 7]
    [0, 0, 8]
