Two women are on either side of a high fence. One of the women, named Apple- server, has a beautiful apple tree loaded with delicious apples growing on her side of the fence; she is happy to supply apples to the other woman whenever needed. The other woman, named Apple-eater, loves to eat apples but has none. In fact, she must eat her apples at a fixed rate (an apple a day keeps the doctor away). If she eats them faster than that rate, she will get sick. If she eats them slower, she will suffer malnutrition. Neither woman can talk, and so the problem is to get apples from Apple-server to Apple-eater at the correct rate. A. Assume that there is an alarm clock sitting on top of the fence and that the clock can have multiple alarm settings. How can the clock be used to solve the problem? Draw a timing diagram to illustrate the solution. B. Now assume that there is no alarm clock. Instead Apple-eater has a flag that she can wave whenever she needs an apple. Suggest a new solution. Would it be helpful for Apple-server also to have a flag? If so, incorporate this into the solution. Discuss the drawbacks of this approach. C. Now take away the flag and assume the existence of a long piece of string. Suggest a solution that is superior to that of (b) using the string.

Part d: float check string has a method s. isdigit() that returns true if string s contains only digits and false otherwise, i. e. s is a string that represents an integer. write a function named float_check that takes one parameter that is a string and returns true if the string represents a float and false otherwise. for the purpose of this function we define a float to be a string of digits that has at most one decimal point. note that under this definition an integer argument will return true. remember “edge cases” such as “45.” or “.45”; both should return true. for example: float_check('1234') returns true float_check('123.45') returns true float_check('123.45.67') returns false float_check('34e46') returns false float_check('.45') returns true float_check('45.') returns true float_check('45..') returns false
