'''Inner Loop: for j in range(6-i):

Iteration 1 (i = 6): j will not execute as range(6 - 6) results in an empty range.

Iteration 2 (i = 5): j will execute once as range(6 - 5) results in range(1).

Iteration 3 (i = 4): j will execute twice as range(6 - 4) results in range(2).

Iteration 4 (i = 3): j will execute thrice as range(6 - 3) results in range(3).

Iteration 5 (i = 2): j will execute four times as range(6 - 2) results in range(4).

Iteration 6 (i = 1): j will execute five times as range(6 - 1) results in range(5).

Now, let's print the output for each iteration:

Iteration 1 (i = 6):

No output from the inner loop as range(6 - 6) is an empty range.

Iteration 2 (i = 5):

Output: 5 (Printed once from the inner loop)

Iteration 3 (i = 4):

Output: 4 4 (Printed twice from the inner loop)

Iteration 4 (i = 3):

Output: 3 3 3 (Printed thrice from the inner loop)

Iteration 5 (i = 2):

Output: 2 2 2 2 (Printed four times from the inner loop)

Iteration 6 (i = 1):

Output: 1 1 1 1 1 (Printed five times from the inner loop)

Therefore, the overall output of the code will be:

5

4 4

3 3 3

2 2 2 2

1 1 1 1 1'''
