How to print a specific row of a matrix in TypeScript

Answer 1

function print_row(matrix: number[][], row: number) {
    const cols = matrix[0].length
     
    let s: string = "";
    for (let j: number = 0; j < cols; j++) {
        s += matrix[row][j] + " ";
    }
    console.log(s);
}
 
   
    
const matrix: number[][] = [ [ 4,  2,  9, 16, 29], 
                             [ 7,  9, 16, 29,  4], 
                             [ 9, 18, 29,  4,  7], 
                             [13, 29,  5,  7,  9], 
                             [29,  4,  7,  9, 18] ];
   
const rows: number = matrix.length;
 
print_row(matrix, 0);
   
print_row(matrix, 3);
 
 
       
         
         
/*
run:
         
"4 2 9 16 29 " 
"13 29 5 7 9 " 
         
*/
