Draw a Crow's feet ERD using the following information.
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…

Two cells are adjoining in the event that they share a side. Thusly, every cell (x, y) has precisely three neighbors: (x+1, y) (x−1, y) (x+1, y−1) in case x is even and (x−1, y+1) in any case. At first a few cells are contaminated, all the others are sound. The course of recuperation starts.

- Suppose that you are given an n × n checkerboard and a checker. You must move the checker from the bottom edge of the board to the top edge of the board according to the following rule. At each step you may move the checker to one of three squares: 1. the square immediately above 2. the square that is one up and one to the left (but only if the checker if not already in the leftmost column) 3. the square that is one up and one to the right (but only if the checker is not already in the rightmost column). 1 Each time you move from square x to square y, you receive p(x, y) dollars. You are given p(x, y) for all pairs (x, y) for which a move from x to y is legal. Do not assume that p(x, y) is positive. design a recursive backtracking algorithm that determines the maximum amount of money you can recieve, when moving a checker frmo somewhere on the bottom row to somewhere on the top row. your algorithm is free to pick any squrre along the bottom row as a starting point and any square along…arrow_forwardwith T=4, n=12 and A=(3,5,8,8,9,16,29,41,50,63,64,67).

To check whether the 3 points lie on the same line, we use the distance formula. If P, Q and R are three collinear points, then: Distance from P to Q + Distance from Q to R = Distance from P to R PQ + QR = PR The distance between two points (x1, y1) and (x2, y2) is given by Hence, we can easily find the distance between the points P, Q and R, with the help of this formula.

- A consumer can withdraw up to $500 per day from an ATM. If a customer withdraws more than $300, the service charge is 4%. It tells the consumer of inadequate cash and offers to withdraw the money for a fee of $25.00. The ATM won't let you withdraw money if your account is empty or has a negative balance. If the withdrawal exceeds $500, the ATM informs the customer of the maximum withdrawal amount and refuses the withdrawal. Write an algorithm that allows customers to enter withdrawal amounts. The algorithm then verifies the account balance, debits the customer's account for the amount withdrawn plus any service fees.arrow_forwardYou are asked to determine the value of the decision parameter p used in Bresenham's circle drawing algorithm.

Maria tells Bella that she is thinking of a number between 1 and 10, and then Bella tries to guess the number.

As much as Maria likes playing the game with Bella, Bella is very excited to play the game all the time.

At first, there is only one tree with roots. The players take turns, Alice begins. At one point, Alice has to pick up any empty underground tree roots (or shrubs) and remove them. Bob, on the other hand, has to pick out any part of the empty leaves and remove them from the tree (or trees). (Please note that Bob always takes some depth from the leaves of the first tree.) It is not allowed to skip the turn. The game ends when the player is unable to take a chance. Alice's goal is to reduce the number of turns made by both players, while Bob wants the number to be greater. Considering that they both played very well, how many turns did they make last.

You can take a few leaps. Assume you're at present at point (y might be negative) and hop for the k-th time. You can: either leap to the point y+k or on the other hand leap to the point y−1. What is the base number of hops you want to arrive at the point x? Input The main line contains a solitary integer t (1≤t≤1000) — the number of experiments. The solitary line of each experiment contains the single integer x (1≤x≤106) — the objective point. Output For each experiment, print the single integer — the base number of leaps to arrive at x. It very well may be demonstrated that we can arrive at any integer point x.arrow_forward
