Final answer:
The output of the nested loop is a pattern of numbers being printed in separate lines.
Step-by-step explanation:
The output of the nested loop is as follows:
- The first iteration of the outer loop prints the numbers 1, 2, 3, and 4 in separate lines, followed by a line break.
- The second iteration of the outer loop prints the numbers 1, 2, and 3 in separate lines, followed by a line break.
- The third iteration of the outer loop prints the numbers 1 and 2 in separate lines, followed by a line break.
- The fourth and final iteration of the outer loop prints the number 1 in a line, followed by a line break.
