Answer 1

function displayTransposeMatrix(matrix) {
    const rows = matrix.length;
    const cols = matrix[0].length;
 
    for (let i = 0; i < cols; i++) {
        let s = "";
        for (let j = 0; j < rows; j++) {
             s += matrix[j][i] + " ";
        }
        console.log(s);
    }
}
 
const matrix = [  [9, 0, 7, 1],
                  [4, 5, 6, 3],
                  [2, 8, 4, 0] ];

displayTransposeMatrix(matrix);
