Question 1For each of these answers, give me a numerical expression that only includes numbers, addition, subtraction, multiplication, division and/or exponentiation. I don't want factorials or more complex notation. It doesn't have to be completely reduced, or calculated out, but it should be clear.
Part A: If the program to the right receives "5 1" on standard input, how many lines will it print?
Part B: If the program to the right receives "8 0" on standard input, how many lines will it print?
Part C: If the program to the right receives "3 3" on standard input, how many lines will it print?
Part D: Suppose I have 7 cities, numbered 1 through 7, that I want to visit, starting with city 1. There is a road from each city to each other city, and I can only visit each city once. In how many different orders can I visit all of the cities?
Part E: Suppose I am playing fantasy football, and I need to select a team with four running backs and two quarterbacks. And suppose that there are 75 running backs and 32 quarterbacks to choose from. How many different teams can I choose?
Part F: In class, I went over a topcoder problem called SimpleRotationDecoder, where a three-letter, lower-case password was required to decode a string containing n lower-case letters and spaces. We didn't know the password, so we performed an enumeration. How many elements did we enumerate?
