You are not told how many teams are participating but you do know that: Each team has a name, which is one of the uppercase letters A-Z. No two teams have the same name, so there are a maximum number of 26 teams. Each team has the same number of members. No two runners cross the finish line at the same time – i.e. there are no ties. At the end of the race we can write the results as a string of characters indicating the order in which runners crossed the finish line. For example: ZZAZAA We can see there were two teams: A and Z. Team A’s runners finished in 3rd, 5th and 6th place. Team Z’s runners finished in 1st, 2nd and 4th place. Scoring the race Each runner is assigned a score equal to their finishing place. In the example above team Z’s runners achieved scores of 1, 2 and 4. Team A’s runners scores were 3, 5, and 6 respectively. The team’s score is the sum of the members score divided by the number of people on…arrow_forwardAssuming that p and r are false and that q and s are true, find the truth value of each proposition in Exercises 14-22.arrow_forward
- Transcribed Image Text A student took four quizzes in a term and would like to compute their average. He also would like to know what will be the remarks. Follow the range of grades and its equivalent remarks, and then fill-up the table below: 100-95 - Excellent 94-90 – Very Satisfactory 89-85 - Satisfactory 84-80 - Fine 79-75 - Fair 74 and below - Poorarrow_forwardLocate a Letter Write a program that requests a letter, converts it to uppercase, and gives its first position in the sentence “THE QUICK BROWN FOX JUMPS OVER A LAZY DOG.” See Fig. 3.31.arrow_forwardConvert Months Write a program that allows the user to enter a whole number of monthsand then converts that amount of time to years and months.

- Problem Description: Standard telephone keypads contain the digits zero through nine. The numbers two through nine each have three letters associated with them (Fig. 1). Many people find it difficult to memorize phone numbers, so they use the correspondence between digits and letters to develop seven-letter words that correspond to their phone numbers. For example, a person whose telephone number is 686-2377 might use the correspondence indicated in Fig. 1 to develop the seven-letter word “NUMBERS.” Every seven-letter word corresponds to exactly one seven-digit telephone number. A restaurant wishing to increase its takeout business could surely do so with the number 825-3688 (i.e., “TAKEOUT”). Fig. 1: Telephone keypad digits and letters. Every seven-letter phone number corresponds to many different seven-letter words, but most of these words represent unrecognizable juxtapositions of letters. It’s possible, however, that the owner of a barbershop would be pleased to know that the…arrow_forwardQuestion 4 - Algorithm Design Imagine you are a treasure hunter standing at one side of the river. 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_forwardAge Write a program that requests your date of birth as input and tells your age.

- Celebrity problem A celebrity among a group of n people is a person who knows nobody but is known by everybody else. The task is to identify a celebrity by only asking questions to people of the form: ”Do you know him/her?” Solution Select two people from the group given, say, A and B, and ask A whether A knows B. If A knows B, remove A from the remaining people who can be a celebrity; if A doesn’t know B, remove B from this group. Solve the problem recursively for the remaining group of people who can be a celebrity Which design strategy does the following solution use? A-)Decrease-by-a-constant factor algorithm B-)Variable-size-decrease algorithm C-)Decrease-by-a-constant algorithm D-)Divide-and-Conquerarrow_forwardWrite a program that requests a three-part name and then displays the middle name.
