1. In this lab assignment we will be using the vim or emacs editor in addition to the commands we have already learned. Open a shell terminal and create a file named in your home directory (use only lowercase letters). In this lab you will construct a few short Perl programs that perform the actions specified below.
List of tasks
1. The following is a section of a program. Show the value of each variable at each step:
@array = (0, 2..6,"abc"); what is @array?
$a = pop(@array); what is $a?
$b = shift (@array); what is $b?
what is @array?
2. Read each of the words contained in the array @ARGV. Print words and the number of their occurrence to standard output line by line (note: case matters here). For example, if your script is called "count.pl", then executing ./count.pl the test program Test the word generates
3. Read in the file dna.seq (in ~afigueroa/csci2344/lab9) and count the number of As, Ts, Cs. and Gs. Print the percentage of each nucleotide. Note: your program should be case insensitive.
