Implement this in C, Python and Go:

global shared int i = 0

main:
    spawn thread_1
    spawn thread_2
    join all threads (wait for them to finish)
    print i

thread_1:
    do 1_000_000 times:
        i++
thread_2:
    do 1_000_000 times:
        i--

In this exercise you should take advantage of the starter code found in the subdirectories corresponding to the three different programming languages. Fill out the missing code and make sure your program is working before committing and pushing the changes to your repository.

Finally, create a new file called RESULT.md inside this directory explaining what happens and why. Remember to add, commit and push the new file.
