This sum is going to affect the game status. The game status can be one of three values. It can be the currently playing game status or it could be won, or it could be lost. The thing is this game status can be computed so we don't really need to put it on the state. So what I'm going to do is I'm going to create a new function here and call it game status. And the goal of this function is to compute the game status at any point. So the first thing that we need is the sum of selected number. Let's put that in a variable, call that sum selected. We can compute the sum of selected numbers from the selected IDs that we put on the state. Cause every time we select a number here we place its index ID on the state. In fact this selected…
