# 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.
