+## Correct the mistakes of the character recognition software
+
+https://www.codewars.com/kata/577bd026df78c19bca0002c0
+
+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.
