    Write separate Perl scripts for each of the given requirements. Mentioned input data files are attached with this posting. In each case command to run the script from the command line should look like:

    COMMAND_PROMPT> script_number.pl input_data_file.txt

    [1] A script script_1.pl that replaces each instance of "th" with "TH" in file part1.txt. The script should print the file to the screen, not just the replaced lines.

    [2] A script script_2.pl to look for lines in the file part2.txt containing a period, question mark, or comma at the end of the line. When these lines are found, print only the part of the line that occurs after the word "it" (case insensitive).

    [3] A script script_3.pl that prints only words (not the entire line) in the file part3.txt on a word boundary that have the letter "p" or "P" in them (i.e. words begin/end with P/p).
