Answer 1

The problem is that all your different outputs are independent from each other. Just consider a case like

03

where the first digit would be substituted correctly, but afterwards you increment the index and print the raw digit 3 during the same iteration.
Instead, you should only execute one output during each iteration, a switch statement or an if-else if-else statement will suit. Also, you need to rethink when to advance the index additionally to the increment at the end of each iteration.
