A very successful cinema director named "Chef" decided to solve the problem. When a customer wants to buy a ticket, the clerk at the ticket window asks the visitor if he or she needs a rest area, and if so, which one: left, right, or both. We know that in the audience they are expected to appear, their L needs a left-handed position, their R needs a right one, Z does not need a single one and B needs both. Your job is to count the number of people who can attend the show. In the theatre there are N rows with each M seat. There is only one lounge between the two adjacent seats. Seats at the beginning and end of the row have two armrests.

A hardware store is selling steel rods of various lengths. However, customers sometimes want to buy rods that the store doesn't carry. For example, if the store only carries 10cm and 30cm rods and a customer wants to buy a 25cm rod, then the order cannot be fulfilled. To boost sales, the store has come up with an idea to weld two rods together to make a longer rod. For example, if the store only carries 3cm and 5cm rods and a customer wants to buy a 8cm rod, then the order can be fulfilled by welding together 3-cm and 5-cm rods. Since rod welding can compromise the strength, the store will only weld up to TWO rods together. More precisely, this means, an order for x cm can be fulfilled if there is a single rod of length x or there are two rods (potentially of the same length) whose combined length is x. Your Task: Write a function process Orders (orders: List[int], sizes:List[int]) -> List[bool] to determine whether or not each of the given orders can be fulfilled. Here, orders is a…
A chess knight, on one turn, moves either two squares vertically and one horizontally, or two horizontally and one vertically. If we consider a knight starting at the point ⟨x, y⟩ in Z × Z, it has eight possible moves, to ⟨x+1,y+2⟩,⟨x+1,y−2⟩,⟨x−1,y+2⟩,⟨x−1,y−2⟩,⟨x+ 2, y + 1⟩, ⟨x + 2, y − 1⟩, ⟨x − 2, y + 1⟩, or⟨x − 2, y − 1⟩. (a) Prove that given any two points ⟨x, y⟩ and ⟨x′, y′⟩ in Z × Z, there is a sequence of knight moves from the first point to the second. (b) Let a and b be different positive naturals. An (a, b)-knight also has eight possible moves, from ⟨x,y⟩ to ⟨x±a,y±b⟩ or ⟨x±b,y±a⟩. What conditions on a and b allow the (a, b)-knight to go from any point in Z × Z to any other? Prove your answer. (c) If a and b do not meet the conditions of part (b), exactly which points can the (a,b)- knight reach from ⟨x, y⟩
We have n glasses which can hold a varying amount of liquid. We will say that glass1 is size q1 quarts and glass2 is size q2 quarts, etc. We now give you a size, say x quarts. You must give me a glass of exactly x quarts. You are allowed to fill any glass to exactly its size and to pour any liquid from one glass into another. When you pour, you either have to empty the glass you are pouring from or fill the glass you are pouring into. Can you do it?More concrete example: G1 has size 10 quarts. G2 has size 4 quarts. G3 has size 1 quart. You can get a 5 quart drink by filling G1, pouring 4 quarts from it into G2 and 1 quart of it into G1. After that, G1 has exactly 5 quarts. In the same problem, we could get 8 quarts by filling G2 twice and emptying it into G1 twice. Given This: Write an algorithm to do this and determine its complexity.
Suppose a person can buy a chocolate bar from the vending machine for $1 each. Inside every chocolate bar is a coupon. A person can redeem 3 coupons for one chocolate bar from the machine. This means that once a person has started buying chocolate bars from the machine, he/she always has some coupons. A person would like to know how many chocolate bars can be bought, if a person starts with N dollars and always redeem coupons, if he/she has enough for an additional chocolate bar. For example: With 3 dollars a person could buy 4 chocolate bars after purchasing 3 bars giving him/her 3 coupons and then redeeming the 3 coupons for one bar. This would leave him/her with one extra coupon. Thus, will have 4 chocolate bars and still have one coupon leftover. For 11 dollars, a person can have 16 chocolate bars and still have one coupon leftover. For 12 dollars, a person can have 17 chocolate bars and have two coupons leftover. Write a complete Python program that prompts a buyer to input…
There are four people who want to cross a rickety bridge; they all begin on the same side. You have 17 minutes to get them all across to the other side. It is night, and they have one flashlight. A maximum of two people can cross the bridge at one time. Any party that crosses, either one or two people, must have the flashlight with them. The flashlight must be walked back and forth; it cannot be thrown, for example. Person 1 takes 1 minute to cross the bridge, person 2 takes 2 minutes, person 3 takes 5 minutes, and person 4 takes 10 minutes. A pair must walk together at the rate of the slower person's pace. Write the specification of an algorithm that solves the problem.
