[LeetCode] Tenth Line

How would you print just the 10th line of a file?

For 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

# Read from the file file.txt and output the tenth line to stdout.
awk 'NR == 10' file.txt
# 12 ms
