Different error messages for invalid integer index

[nus-se-script]

Steps:

1. When typing the command select 9 for a list size of 8, the error message displayed is "the course index provided is invalid" as shown in the screenshot below.

2. However, when typing the same command select 999999999999999, the error message displayed is "Invalid command format" but the expected output should still be "the course index provided is invalid".

Perhaps can handle the errors when there is an integer overflow?

Team's Response

As seen in the screenshot, this is considered extreme user behaviour. It is unrealistic to assume a TA to have courses/students anywhere close to the tested value.
