Coding Exercise: Tasty Typecasting

Write a program to help you feed your friends at a party by doing some math about square pizzas. Assume the grader defines a string inputStr for you, which is a decimal string meaning the side length L of the pizza in cm. The area of the pizza should be computed using the formula A = L*L. Then, assuming that each person needs to eat 100 cm² of pizza, compute the number of people it can feed, rounded down to the nearest integer. Hint

Example: if inputStr is "17.5", the area will be 306.25 cm², so 3 is the correct output.
