Algorithm Analysis
Start with 102 coins on a table, 98 showing heads and 4 showing tails. There are two ways to
change the coins:
• flip over any ten coins, or
• place n+ 1 additional coins, all showing tails, on the table where n is the number of heads
currently showing on the table.
For example, you might begin by flipping nine heads and one tail, yielding 90 heads and 12 tails,
then add 91 tails, yielding 90 heads and 103 tails.
(a) Model this situation as a state machine, carefully defining the set of states, the start state, and
the possible state transitions.
(b) Optionally, explain how to reach a state with exactly one tail showing.
(c) Consider the following derived variables:
C ::= the number of coins on the table H ::= the number of heads on the table
T::= the number of tails on the table C, ::= parity (C)
H2 ::= parity(H)
T2 ::= parity(T)
Here the parity : Z → {0,1} function is defined as parity(n) = 0 when n is even and 1
otherwise.
Which of these variables is strictly…
Write a detailed algorithm for making a peanut butter and jelly sandwich(or some other everyday activity). You should assume that you are talkingto someone who is conceptually able to do the task, but has never actuallydone it before. For example, you might be telling a young child.
Instructions for Questions 1 through 6. For each piece of pseudocode, give the
runtime in terms of N. Your answer should give an exact value for the number of times
the inner loop runs (i.e. the final value of count), and it should also give the order of
growth of the runtimes using big-Oh notation. You can assume that N "comes out nicely"
with respect to loops. For example, if the loop counts by 2, you can assume it is an even
number, and if it multiplies or divides by 2 each time, you can assume it is a power of 2.
Note: log(N!) is 0(NlogN).

The algorithm should first read the total number of students and then read the height and weight of each student to calculate and print the BMI category A student is considered Underweight if the BMI is less than or equal to 18.5; Normal Weight if between 18.5 and 24.9; Overweight if between 25 and 29.9; and Obese if greater than or equal to 30.arrow_forwardQuestion-2 : The entrance room (or the starting of the maze) is considered as level 1.

He wants to know how much he saves by buying all of his CDs through the club rather than through the music store. The output is the savings. The input is the number of CDs purchased, the club CD price, and thestore CD price. The algorithm should use two processing items: one for the cost of buying the CDs through the club, and the other for the cost of buying the CDs through the store. Write the algorithm using pseudocode.arrow_forward

Answer:arrow_forwardIn various applications, you are often asked to compute the mean and standard deviation of data. The mean is simply the average of the numbers. The standard deviation is a statistic that tells you how tightly all the various data are clustered around the mean in a set of data. For example, what is the average age of the students in a class? How close are the ages? If all the students are the same age, the deviation is 0.

- Python Coding AlgorithmPlease check the task description. Use the test case input as a test case to see if the final code works, as the code's output should be similar to the given sample output. Hopefully, you succeed. TaskIdentify the relationship between the sets of inputs. The inputs represent the wires in a Bulb's Wiring System. Concept-The Bulb system is identical to an electronic circuit, so Basic Circuit Rules and Ohm's Law apply.-Wires in a Series relationship are denoted as Linear, and those in Parallel are denoted as SidebySide-Therefore, the relationships are either Linear or SidebySide. If pairs of wires are neither Linear nor SidebySide, it will be denoted as having Neither relationship.-Wires with similar origins and destinations have a SidebySide relationship. On the other hand, Linear relationships are more complex as they require a continuous and singular wire connection. The flow of electricity starts from the "Start" point and ends at the "End" point.Note: Check…arrow_forwardYou are given the task of analyzing how joyful a person is.

- Coupon collector is a classic statistic problem with many practical applications. The problem is to pick objects from a set of objects repeatedly and determine how many picks are needed for all the objects to be picked at least once. A variation of the problem is to pick cards from a shuffled deck of 52 cards repeatedly and find out how many picks are needed before you see one of each suit. Assume a picked card is placed back in the deck before picking another. Write a program to simulate the number of picks needed to get four cards from each suit and display the four cards picked (it is possible that a card may be picked twice).arrow_forwardYour team was asked to program a self-driving car that reaches its destination with minimum travel time.
