#!/usr/bin/env bash

#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

# Read from the file file.txt and print its transposed content to stdout.
