This program will do the Bezout theorem of two integers for you, giving all the necesary values to express the number as (x * n) + (y * m) = c.
All you have to do is open the command line, go to the directory where the program is located and type "Bezout x y", being x and y the two numbers. Also you can add the program to the path to use it globally.
Compiled binaries for linux and Windows. Bezout.exe for windows and Bezout for linux.
Theoretically it works on MacOs, but not tested.
