Validate the input as follows:

Make sure the numbers of fat grams and calories aren$$t less than $0.$

Ensure that the number of calories entered isn$$t greater than fat grams $\backslash$times $9.$

Once correct data has been entered, the program should calculate and display the percentage of calories that come from fat. Use the following formula:

Percentage of calories from fat $=($Fat grams $\backslash$times $9)-$: calories

Some nutritionists classify a food as $$low fat$$ if less than $30$ percent of its calories come from fat. If the results of this formula are less than $0\mathrm{.}3,$ the program should display a message indicating the food is low in fat.
