How to print a specific row of a matrix in Node.js

Answer 1

function print_row(matrix, row) {
    const cols = matrix[0].length
     
    let s = "";
    for (let j = 0; j < cols; j++) {
        s += matrix[row][j] + " ";
    }
    console.log(s);
}
 
   
    
const matrix = [ [ 4,  7,  9, 16, 29], 
                 [ 7,  9, 16, 29,  4], 
                 [ 9, 18, 29,  4,  7], 
                 [13, 29,  4,  7,  9], 
                 [29,  4,  7,  9, 18] ];
   
const rows = matrix.length;
  
print_row(matrix, 0);
   
print_row(matrix, 3);
 
 
       
         
         
/*
run:
         
4 7 9 16 29 
13 29 4 7 9
