Attempt to recreate git diff functionality.

Used LCS to find LCS line-by-line from each code. then find difference in the intermediate lines.

REFERENCE

diff from git diff attached

git diff does not print the whole file, only the changes portion
does not display that i have deleted a space
does display if a space is added

vs code extension

vs code goes even further, shows the change in each line

ATTEMPTS

diff.py

uses LCS to find Longest matching code, line by line, and then print diff.
other notes in the file

my output

diff2.py

applied the same logic of LCS to each character in the modified lines to get what is modified.
