195. Tenth Line

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

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:

Line 10

Note:

輸出第十行的資料，至少有三種解法，嘗試看看怎麼做。如果不到十筆資料的話，你應該輸出什麼呢？

這邊有一個討論滿值得看看的。

Runtime

# Read from the file file.txt and output the tenth line to stdout.
sed -n 10p file.txt

Memory

# Read from the file file.txt and output the tenth line to stdout.
tail -n+10 file.txt | head -n1
