Can every arbitrary problem be expressed as a language?
In the domain of computational complexity theory, the concept of expressing problems as languages is fundamental. To address this question we need to consider theoretical underpinnings of computation and formal languages. A "language" in computational complexity theory is a set of strings over a finite alphabet. It is a formal construct that can be recognized
