In the above program, two separate outer loops are used. For the first outer loop, again two inner loops are used. First inner loop prints the left side spaces and the second inner loop prints the values. The outer loop continues upto the line 5  5  5  5  5  5  …
With the iteration of the outer loop the iteration of the loop printing the space is decreased and iteration of the loop printing the digits is increased.

This is just the reverse for the second loop.
