Part 6: Boolean Logic Expressions
Boolean expressions are types of logical operations that we can perform on true and false values. Note that the word Boolean is always capitalized because it was named after its inventor, George Boole. Boolean algebra is a very important topic in computer science, and if you haven't learned it before you definitely will in the future. However, for our purposes we are only interested in how we can use them to manipulate binary numbers. The way we use them on binary numbers is by treating 1 as true and 0 as false. From this point on I will be using 0 and 1 instead of false and true.
There are many types of Boolean expressions, but the three most important ones are AND, OR, and NOT.
AND takes 2 operands and will output 1 if they are both 1, or 0 otherwise
OR takes 2 operands and will output 1 if either one is 1, or 0 if neither is 1
NOT takes 1 operand and reverses it: 1 becomes 0, and 0 becomes 1
We can represent this behavior using something called a…

There are n (a positive integer) stones on the river. They are aligned on a straight line and at the nth stone, there is treasure waiting for you. Your target is to reach the nth stone. For each move, you have the choice of either walking (move one stone ahead) or leaping (move two stones ahead). Also, you are not allowed to travel backwards. Design an algorithm that calculates the number of ways (sequences of walks/leaps) that get you to the treasure stone. You should clearly explain the algorithm and demonstrate the correctness of the algorithm with a complete proof. Here is an example. For n = 1 5, there are 8 ways: Method 1: walk → walk → walk → walk → walk Method 2: walk → walk → walk → leap Method 3: walk → walk → leap → walk Method 4: walk → leap → walk → walk walk Method 5: leap → walk → walk → Method 6: leap → leap walk Method 7: leap → walk → leap Method 8: walk → leap leaparrow_forwardThis device was used the US Bureau of Census in 1880's.

Each book has a title in this alphabet and you hope that the books are arranged in lexicographical order on the bookshelves. You would like to know whether the order of the books uniquely determines the order of the characters of the alphabet, or if there is insufficient information, or whether even such an order cannot exists (meaning that someone must have shuffled the books). Think of the input as a list of words without spaces from the alphabet "a-z", and the question is the order of the characters "a-z" in the examined alphabet. Try to find an algorithm which solves this problem in time linear in the size of the input (that is, the number of characters on input). You may assume that each character appears at least once. Don't assume that the size of the alphabet is a fixed constant (like 26); treat it as a variable n, and let L be the total number…arrow_forward
