Correct the mistakes of the character recognition software

Character recognition software is widely used to digitise printed texts. Thus the texts can be edited, searched and stored on a computer.

When documents (especially pretty old ones written with a typewriter), are digitised character recognition softwares often make mistakes.

Your task is correct the errors in the digitised text. You only have to handle the following mistakes:

• S is misinterpreted as 5
• O is misinterpreted as 0
• I is misinterpreted as 1

The test cases contain numbers only by mistake.
