An undecidable problem is a decision problem for which no algorithm can be constructed that always leads to a correct yes-or-no answer for all possible inputs. In other words, there is no computational method that can determine the answer to these problems in a finite amount of time for every possible case. One of the most famous examples of an undecidable problem is the **Halting Problem**.
