- In this game, one flyand three frogs are placed randomly on a board with the size 7x7.In each iteration, they move randomlywithin the board, and the simulation stops when one of the frogs eats the fly.Fly and frogs are essentially creatures that can move, make noise, and eat. Frogs can move up to 2squares in any direction, and flies can move up to 1. Frogs make the "Croak! Croak!" sound, and fliesmake "ZzzZZz!". Since frogs should not eat their kind, a function of "isEatable" should also beimplemented in decision making. A variable or function to check if the fly is alive is also required as aterminate condition for simulation.In each iteration, an 'f' character represents frogs' position on board, and an '*' character is used torepresent the position of fly.

The number of fairies participating in this competition is not known ahead of time. Before flyinghigh, each fairy goes through a pixie dust machine and gets sprinkled with the pixie dust. The pixie dust allows themto fly and perform their special talent high up in the sky. Pixie dust can be of any one of the 4 colours (red, blue,yellow, and green) and each colour has a dust strength in the following ranges (dust strength determines roughlyhow high a fairy can fly):Colour StrengthRed 40 - 49Blue 30 - 39Green 20 - 29Yellow 10 - 19Write a Python program, in a file called fairyland.py, to include the following functions:• function main that repeatedly obtains a fairy’s name (from the user) and, using other functions, determinesthe colour of pixie dust that the fairy has been dusted with, the height of the fairy’s flight (based on thatcolour), and keeps…arrow_forwardCorrect answer will be upvoted else downvoted. Computer science. You have w white dominoes (2×1 tiles, the two cells are hued in white) and b dark dominoes (2×1 tiles, the two cells are shaded in dark). You can put a white domino on the board in case both board's cells are white and not involved by some other domino. Similarly, you can put a dark domino if the two cells are dark and not involved by some other domino. Would you be able to put all w+b dominoes on the board if you can put dominoes both on a level plane and in an upward direction? Input The main line contains a solitary integer t (1≤t≤3000) — the number of experiments. The primary line of each experiment contains three integers n, k1 and k2 (1≤n≤1000; 0≤k1,k2≤n). The second line of each experiment contains two integers w and b (0≤w,b≤n). Output For each experiment, print YES in case it's feasible to put all w+b dominoes on the board and negative, in any case. You might print each letter…arrow_forward
- Part C: Function, for and plotting We did a project in the lecture on calculating the free fall speeds and plotting them on a graph. This part is similar to the project. An engineer has derived a relationship between the force applied to a material and the extension in length that the force would cause. The relationship between force f and extension e is given by: You are asked to plot a graph showing the relationship between force and extension. You are asked to complete the following tasks: Task 1 Write a Python function which returns the value of e for a given input f. Do not use literals (e.g. 5.5, 10) in the expressions for e in the function. Instead you should define constants and use them. Note that the relationship between e and f depends on whether f is bigger than 10 or not, this means you need a certain Python construction in your function. If you can't think of that, have a look at Part A of Lab03.arrow_forwardThe annual snake festival is upon us and all the snakes of the kingdom have gathered to participate in the parade. The chef was tasked with reporting on the parade, so he decided to watch all the snakes first. When he sees the snake first, it will be his head, so he marks the "H". Snakes are long, and when they see the snake finally scurry away, they mark its tail with a "T". In the interim, when the snake is moving around it, or in the time between one snake and the next snake, it marks a '.'. Since the snakes come in a procession and one by one, a valid message would be something like "..H..T...HTH....T.", or "...", or "HT", while "T ...H..H.T", "H..T..H", "H..H..T..T" would be invalid messages (see explanation below). Formally, a snake is represented by an 'H' followed by some (possibly null) '.' and then 'T'. A valid message is one that begins with the (probably zero-length) string '.' and then some (possibly zero) snakes, with some '.'s in between, and finally some (possibly zero)…arrow_forwardComputer Science Investing in stocks is a way to create assets that are supposed to provide financial security over time. In solving this problem, we assume that an investor buys several shares of stock at a certain price. These shares are going to be sold later on for a different price. Obviously, if the selling price is higher than the acquisition price, the investor makes a profit, registering capital gain. If the shares are sold at a lower price, the investor has a loss, which marks a negative capital gain. This whole process is done over a period of time, and you are required to create a scenario for buying and selling shares. The assumption is that the investor sells shares in the order in which they were purchased. The goal is to calculate the capital gain over time. Suppose that you buy n shares of stock or mutual fund for d dollars each. Later, you sell some of these shares. If the sale price exceeds the purchase price, you have made a profit—a capital gain. On the other…arrow_forward

The rules are as follows: If the house is next to a lake, then the treasure does not go in the kitchen If the tree in the front yard is an elm, then the treasure is in the kitchen The tree in the front yard is an elm or the treasure is buried under the flagpole If the tree in the backyard is an oak then the treasure is in the garage. You observe that the house where the treasure is hidden is next to a lake. Where is the treasure? discrete matharrow_forward
