Modify your program so that, instead of asking the user for values, it uses loops to make each variable iterate over its valid values. For each possible value of R1, we want to generate each possible value of R2. For each of these, we want to generate each possible value of R3. When we are there, we compute the payoff for this specific triplet of values and display it on the screen, like so; Example Output: 1 1 1 3 3 3 1 1 3 3 3 payoff is 1 2 payoff is 1 < Some output removed here to keep this short > 1 2 3 payoff is 4 payoff is 5 payoff is 3
