Tenth Line

Desicription

Given a text file file.txt, print just the 10th line of the file.

Example:

Assume that file.txt has the following content:

1
2
3
4
5
6
7
8
9
10
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:

1
Line 10

Note:

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