Multiple choice technology programming languages $input = “abdce”; $output = $input =~ tr/abc/123; print $input; print $output 12d3e 3 12d3e 5 12d3e 1 Error 12d3e null string Reveal answer Fill a bubble to check yourself A Correct answer Explanation The tr/abc/123 operator transliterates: a→1, b→2, c→3. Other characters pass through. 'abdce' becomes '12d3e'. The tr operator returns the number of transliterations made (3), which becomes $output's value. Print outputs both strings.
