Step III: #9 #9 #9 __ #1 __ 9$ 8$ 5$ 4$ 3$ 0$

Note -

Change to any number will be made once only.

Blanks in each step are numbered as 1, 2, 3 and so on, progressing form left to right.

If the original form of a number is changed once then it would not be considered for rearrangement.

The positions are counted from left to right such that the leftmost position is treated as 1 and so on.
