Instructions:
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.
Solution
Output
Thoughts:
I have used the replaceAll() string function to replace all 5s, 1s and 0s to S, I and O. And functional chaining to have a concise and readable code.
