👉 Countertripping is a concept in the field of computer science and artificial intelligence, where two programs or algorithms are executed simultaneously on different inputs. In other words, one program performs an action (such as printing "Hello World" to the console) while another program performs an opposite action (such as executing a function that prints "World" to the console). The goal is to find a way to execute these two programs without interfering with each other or causing any unintended consequences.
