For this exercise you are required to make a copy of thefollowing script into a file

#!/bin/tcsh -f

echo “guess the number”

set answer = $<

set goal= `tr -dc A-Za-z0-9 </dev/urandom | od -d | head -c 10 | tr -d 0 | tr -d ‘ ‘`

set count = 1

while ($answer != $goal )

    if ($answer <$goal ) then

        echo “too small”


        echo “too large”


    @ count ++

    set answer =$<


echo “correct!”

echo “using $count rounds”
