Question
Transcribed Image Text:In this programming, you learn more about efficiency of algorithms based upon run time. Hence
you need to use time() or clock() function to measure the execution of sorting algorithms and
bubble binary-search. You may use the program we have been working in class since last week. Here you
are asked to use the following to create an array, Num[8192].
-Size of the array
bubble
●くろまる
bubble
bubble
Use srand() to generate a random number each time;
o Range of the random numbers should be 0... 10000.
The expected outcome looks like the following:
Binary sort takes xxx seconds.
Selection sort takes xxx milliseconds.
Implement the binary search for the following numbers; there would be no match depending on
the generated Num[8942]
Insert
time-measurement statements to print it in seconds or milliseconds.
O We will be working on it in class using clock ();
Find these numbers and print the number of If-comparisons for 71, 9997, 5000, 2, 3015;
Binary search 71 takes 8 comparisons-found
Binary search 9997 takes 13 (log28192 = log2 213) comparisons - not found

- If a team is unable to complete all the points of work allocated for an iteration, the team should use the number of points that were completed as basis for the work for the next iteration. True/Falsearrow_forwardProblem2: A square matrix can be represented by a two-dimensionalarray with N rows and N columns. You may assume a maximum size of 50 rows and 50 columns. 1. Write an algorithm MakeEmpty(n), which sets the first n rows and n columns to zero. 2. Write an algorithm Add(M1, M2, M3), which adds two matrices M1 and M2 together to produce matrix M3. 3. Write an algorithm Subtract(M1, M2, M3), which subtracts matrix M2 from matrix M1 to produce matrix M3. 4. Write an algorithm Copy(M1, M2), which copies matrix M1 into matrix M2.arrow_forwardInput a list of employee names and salaries and store them in parallel arrays. End the input with a sentinel value. The salaries should be floating point numbers Salaries should be input in even hundreds. For example, a salary of 36,510 should be input as 36.5 and a salary of 69,030 should be entered as 69.0. Find the average of all the salaries of the employees. Then find the names and salaries of any employee who's salary is within 5,000 of the average. So if the average is 30,000 and an employee earns 33,000, his/her name would be found. Display the following using proper labels. i need to do this in raptor.arrow_forward
