- In exercises 15 and 16, state and prove a loop invariant for the given pseudocode.arrow_forwardCelebrity 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_forwardIntroduction Some number of teams are participating in a race. 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_forward
- EXERCISE No.3 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 – Poor REQUIREMENTS: 1. Write the corresponding algorithm a. Narrative b. Pseudocode 2. Create the equivalent flowchart based on the algorithm of the given problem 3. Construct the program and record your screen display result | Create the ff: ALGORITHM NARRATIVE PSEUDOCODE FLOWCHART QUESTIONS 1. What are the data needed for the solution of the program to produce the desired output? 2. What statements in the program that determine the average grade remarks? 3. What have you observed in using switch statement in this program than using if-else statement?arrow_forwarduse numbers in second picture rather than first pleasearrow_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. See Fig. 3.38. The programshould use both integer division and the Mod operator.arrow_forward
- Exercise 1: (Algorithms and Flowcharts) To Calculate Total Marks of a students (Marks = C1 +C2 + C3 )arrow_forwardSequential Money Problem (Coin Row)• Suppose there are n coins lined up side by side on a table; Let the values of these coins be c₁, c₂, ..., cn (the valuesthey do not have to be different from each other, there may be more than one coin of the same value on the table; but all positive).• The goal is not to take two adjacent coins on the table side by side.collecting the largest total valuable coins from the table, provided that The algorithm that solves the Ordered Money problem;a. By using the brute-force method, evaluating all possible valid alternatives and reaching the result (with the "exhaustive search" method),b. Write the "recurrence" equation that describes the problem directly (without using the dynamic programming technique). Describe the time complexity of each of your algorithms for both of the above spelling.arrow_forward14. _____ variables take on values in an experiment.

- Sort Three Numbers Write a program that requests three different numbers as input and then displays the numbers in order. Use a Procedure named Sort to which the three values are passed ByRef and use a “Swap” procedure similar to the one in Example 3. See Fig. 5.36.arrow_forwardfor( ( } total = total + number; Fig. 2 Finish the for loop in Fig. 2. The loop will total the variable number six times.
