"WebOptimal substructure is a core property not just of dynamic programming problems but also of recursion in general. If a problem can be solved recursively, chances are it has an optimal substructure. Optimal substructure simply means that you can find the optimal solution to a problem by considering the optimal solution to its subproblems. " - Optimal substructure property is utilized by
