Systems Programming Write a program that prompts the user to enter a positive integer and then compute the sum of all the digits of the number, maximum of all the digits and minimum of all the digits. For example if the user enters 2784, then the program reports 21, 8, and 2. The program should work for any number of digits up to ten. Write three different functions sum(), max(), and min() to return the sum, max, and min of all digits. Submit the program with: 1. Statement of the problem (as given above) 2. Compilation results (Get a screen shot and paste it to MSWORD file) 3. Show the results (Get a screen shot and paste it to MSWORD file) 4. Conclusions

Jess wants to buy a bag of mixed nuts (peanuts, almonds, and cashews in equal quantities). She noticed that a 1-lb bag is $6.49, but she could separately buy peanuts for $2.97 per pound, almonds for $7.95 per pound, and cashews for $6.96 per pound. Would it be a better deal to buy the store mix or make her own mix?

A Boolean Ring is a ring R with identity in which $x^2 = x$ for all $x \in R$. In other words, a Boolean Ring is a ring with identity in which every element is an idempotent. (a) Show that if S and T are Boolean Rings, then their product $S \times T$ is also a Boolean Ring. (b) Consider $\mathbb{Z}_2 \times \mathbb{Z}_2 \times \dots \times \mathbb{Z}_2$, a product of n copies of $\mathbb{Z}_2$. Show that this ring is a Boolean Ring. (c) Let R be a Boolean Ring. Show that every $a \in R$ is its own additive inverse. That is, show that $a = -a$. [Hint: expand $(a + a)^2$.] (d) Show that every Boolean Ring is commutative. [Hint: expand $(a + b)^2$.]
