1. Consider sets AA and BB with |A|=9|| and |B|=19..
How many functions f:A→B are there?
Note: Leave your answer in exponential form. (Ex: 5^7)
2. Consider functions f:{1,2,3}→{1,2,3,4,5,6}.
How many functions between this domain and codomain are
injective?
3. A combination lock consists of a dial with 39 numbers on it.
To open the lock, you turn the dial to the right until you reach
the first number, then to the left until you get to the second
number,...

Suppose you are playing a game of five-card poker where you are
dealt a hand of 5 cards from a standard deck of 52 playing cards.
Each card has one of 13 values, 2,3,…,10,J,Q,K,A2,3,…,10,J,Q,K,A,
and one of 4 suits, ♡,♢,♠,♣♡,♢,♠,♣
A hand called a royal flush consists of cards of
the values 10,J,Q,K,A10,J,Q,K,A, all from the same suit. For
instance, a royal flush with hearts would be
10♡,J♡,Q♡,K♡,A♡10♡,J♡,Q♡,K♡,A♡.
Now, actually getting a royal flush in poker is incredibly rare (in...

Strings
The example program below, with a few notes following, shows how
strings work in C++.
Example 1:
#include <iostream> using namespace std; int main()
{
string s="eggplant";
string t="okra";
cout<<s[2]<<endl;
cout<< s.length()<<endl; //prints 8
cout<<s.substr(1,4)<<endl; //prints ggpl...kind of
like a slice, but the second num is the length of the
piece
cout<<s+t<<endl; //concatenates: prints eggplantokra
cout<<s+"a"<<endl;
cout<<s.append("a")<<endl; //prints eggplanta: see
Note 1 below
//cout<<s.append(t[1])<<endl; //an error; see
Note 1
cout<<s.append(t.substr(1,1))<<endl; //prints
eggplantak; see Note 1
cout<<s.find("gg")<<endl;
if (s.find("gg")!=-1)
