Given the number of calories Knightro has worked out, he wants to determine how many more calories he needs to earn before he earns another smoothie. The variable's names are total$\_$cal, which stores the calories Knightro has already earned. Each smoothie is worth $250$ calories. Store the answer as the variable s$.$ HINT: Knightro can earn multiple smoothies per workout. You are only looking for the next. Therefore you cannot assume that the amount of calories he has earned is less than $250.$ Do not include spaces or parentheses in your solution.
