  • изображение Adam R. Program to permutate string and run again with all upper and lower combinations $150.00 USD

    “WOW! AAAMMMAZING! Wayyy under schedule and the work and instructions for the program were so damn perfect. I could not be any more impressed and happy with the outcome. 2 days and my project was complete w/ a GUI! If you get a quick reply on your project from others, I will worry a bit. Even though Yong is from China, which might scare some, theyre english is great and even had me clarify stuff that I didnt think of for the project. Code is clean! Still speechless. Thank you so much. Hidden gem!”
