👉 In mathematics, a "subproblem" is an intermediate or simpler problem that is related to but distinct from the original problem. It is often used in computational problems where one has to solve several smaller versions of the same problem simultaneously. For example, consider the following two problems: 1. Find all prime numbers less than 20. 2. Determine if a given number is divisible by 3 or not. In these cases, each problem involves solving a subproblem that is related to and distinct
