How to convert a specific row of a matrix to a string in Node.js

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],
  [7,  18, 81,  2,  6, 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:
 
7 18 81 2 6 5
 
*/
