In the Grover's algorithm, the solution is already in the Oracle in order to mark winning state(s). I just wonder if we already know the solution, why do we need to run a circuit ?

In the Grover's algorithm, we actually don't know the right answer or the winner state(s), it's search problem to find the state(s) that verify this equation : F(x) = 1, You can imagine this algorithm as hidden layer used by other mechanisms and techniques to speed up their executions
