Someone built a calculator app that displays "hello world" in the output and shows "2+2" as the calculation. You know, because every CS student's journey starts with printing "hello world" and ends with... still printing "hello world" but with extra steps and a UI framework. The calculator doesn't even pretend to calculate anything. It's just hardcoded to show the sacred greeting regardless of what math you're attempting. Pretty much sums up that final project you threw together at 3 AM the night before it's due—looks functional from a distance, actually does nothing useful, but hey, it compiles and displays text on screen. Professor gives you a B- for effort. The real flex is having parentheses buttons on a calculator that only outputs "hello world". That's some next-level commitment to the bit.
