Instead of 'filename', enter the name of the file you want to work on. The
two files should be in the same directory for this to work. Otherwise, you
will need to enter the full path of the file,
perl new_liner /path/to/filename
You should get output like this:

Consider what happens if you call running sum a second time (say as

The sum of (5 6) is 11
The sum of (5 6 2 7) is 31
