👉 Undetestability is a concept in computer science and programming theory that refers to the difficulty of testing an algorithm or program. In other words, it's not possible to test whether a given algorithm is correct or not without knowing its implementation details. Undetestability can be thought of as a measure of how well a program's correctness can be verified by another program using different inputs and possibly different algorithms. For example, if we have an algorithm that checks if a number is prime, undetestability would
