Answer 1

function convertRowOfMatrixToString(matrix, row) {
    const cols = matrix[0].length;
    let result = '';
   
    for (let j = 0; j < cols; j++) {
        result += matrix[row][j].toString();
        result += ' ';
    }
   
    return result.trim();
}
 
const matrix = [
  [4, 7, 9, 18, 29, 0],
  [1, 9, 18, 99, 4, 3],
  [9, 17, 89, 2, 7, 5],
  [19, 49, 6, 1, 9, 8],
  [29, 4, 7, 9, 18, 6]
];
 
const row = 2;

const str = convertRowOfMatrixToString(matrix, row);
 
console.log(str);
 
 
 
/*
run:
 
9 17 89 2 7 5
 
*/
