194. Transpose File
Given a text file file.txt, transpose its content.
You may assume that each row has the same number of columns and each field is separated by the ' ' character.
For example, if file.txt has the following content:
name age
alice 21
ryan 30
Output the following:
name alice ryan
age 21 30
accepted result:
less file.txt| awk '{for (i=1;i<=NF;i++) { if (NR==1) {res[i]=$i} else { res[i]=res[i] " " $i} }} END{for (i in res) {print res[i]}}'
