问题描述

Example:
Assume that file.txt has the following content:
Line 1
Line 2
Line 3
Line 4
Line 5
Line 6
Line 7
Line 8
Line 9
Line 10
Your script should output the tenth line, which is:

If the file contains less than 10 lines, what should you output?
-
There’s at least three different solutions. Try to explore all possibilities.
