Write a function named merge-sort in Scheme that takes a list of integers as input and returns a sorted list. (Hint: Use the merge and split-list methods that you just wrote. You will have to cut-and-paste the code into your answer.) For example, • (merge-sort '(5 3 1 2 4)) should return '(1 2 3 4 5) • (every-other '()) should return '()

Question

Write a function named merge-sort in Scheme that takes a list
of integers as input and returns a sorted list. (Hint: Use the
merge and split-list methods that you just wrote. You will
have to cut-and-paste the code into your answer.)
For example,
(merge-sort '(5 3 1 2 4)) should return '(1 2 3 4 5)
• (every-other '()) should return '()

Expert Solution

Step 1

Each point is a list of two values for x- and y- coordinates. # Returns a new list of points sorted on the y-coordinatesdef sort(points):For example, the points [[4, 2], [1, 7], [4, 5], [1, 2], [1, 1], [4, 1]] will be sortedto [[1, 1], [4, 1], [1, 2], [4, 2], [4, 5], [1, 7]]. Write a test program that displaysthe sorted result for points [[4, 34], [1, 7.5], [4, 8.5], [1, -4.5], [1, 4.5],[4, 6.6]] using print(list).
Language: C++ Write a Program with Comments for your code to improve quick sort. The quick sort algorithm presented in the ClassNotes-Sorting, it selects the first element in the list as the pivot. Revise it by selecting the median among the first, middle, and last elements in the list.Explain your Outputs or Answers for the following: (C) Give a list of n items (for example, an array of 10 integers) representing the worst-case scenario. (D) Give a list of n items (for example, an array of 10 integers) representing the best-case scenario. Please compile your answers in a file including all source code with comments, Explain your running Outputs or Answers in (A) ~(D).

PLZ write in SML language. Thank you Write a function maxGroup that determines, for a given integer list, the stored number of the longest consecutive group of equal numbers. For example, maxGroup [2, 9, 8, 8, 8, 7, 9, 1] should return 8 since there are three consecutive 8s in the list. Hint: Solve the problem in two steps. First, determine the length of each group of equal numbers. Then, determine which is the largest.
C++ Nested loops: Print seats. Given numRows and numColumns, print a list of all seats in a theater. Rows are numbered, columns lettered, as in 1A or 3E. Print a space after each seat, including after the last.
