Need help writing pseudocode and flowchart

I am trying to find some help as to how to make a pseudocode and flowchart to design a program that asks for fat grams and calories in a food item.

Validate input as follows:

-Number of fat grams and calories arent less than 0

-Number of calories arent greater than fat grams*9

Once correct data is entered, program should calculate and display percent of calories from fat. Use formula :

Percentage of calories from fat=(fat grams*9)/calories

If the results are less than 0.3, the program should display a message saying that the food is low in fat.

Please help ! thank you !
