Write it, run it, read the output

This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.

TASK

Use the nested loops and n = 4 to print four rows. Each row must print the outer loop variable i four times, followed by one newline after the row.

1 1 1 1 
2 2 2 2 
3 3 3 3 
4 4 4 4
