How to print the corners of a matrix in TypeScript

Answer 1

function printMatrixCorners(matrix: number[][]) {
    console.log("left top corner: " + matrix[0][0]);
    console.log("right top corner: " + matrix[0][matrix[0].length - 1]);
    console.log("left bottom corner: " + matrix[matrix.length - 1][0]);
    console.log("right bottom corner: " + matrix[matrix.length - 1][matrix[0].length - 1]);
}
  
const matrix: number[][] = [
    [1, 2, 3, 4],
    [5, 6, 7, 8],
    [9, 3, 2, 0]
];
   
printMatrixCorners(matrix);
   
   
       
       
/*

"left top corner: 1" 
"right top corner: 4" 
"left bottom corner: 9" 
"right bottom corner: 0"
