# 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.


def correct(string):
    return string.replace('0', 'O').replace('5', 'S').replace('1', 'I')
