👉 In computer science, a "derequisition" is a specific type of resource that can be borrowed or returned to another object. This concept arises in the context of dynamic programming algorithms and its role in solving combinatorial problems. In the context of dynamic programming, a derequisition is a technique used by recursive functions to keep track of the state of the recursion stack during computation. By keeping track of the current state of variables at each step, the function can avoid redundant computations that might occur when
