Write a program to sort an array of random elements using quicksort as follows: 1. Sort the arrays using pivot as the first element of the array 2. Sort the arrays using pivot as the median of the first, last, and middle elements of the array 3. Sort the arrays using pivot as the first element of the array. However., when the size of any sub-list reduces to less than 20, sort the sub-list using insertion sort. 4. Sort the array using pivot as the median of the first, last and middle elements of the array. When the size of any sub-list reduces to less than 20, sort the sub-list using insertion sort. 5. Calculate and display the CPU time for each of the preceding four steps. Example of the median of the first, last and middle elements: 123456780 (median of 1, 5, 0 is 1) 801234567 (median of 8, 3, 7 is 7) To calculate the CPU time, use the header , and clock_t type. You need to cast the duration to float and divide it by CLOCKS_PER_SEC. Depends on the CPU of your computer, your outputs would not be the same as in the sample output below.

In C program language, You are to read 10 numbers from a data file into an array named List. Create another 10 element array named Reverse that is to contain the same items as List but in reverse order. For example, the first element in List will be placed in the last position of Reverse, the second element in List will be placed in the second-to-last position in Reverse, etc. After Reverse has been created, output the contents of both arrays.
C Programming Arraying 102 by CodeChum Admin We've already made arraying/listing the easy way, but how about arraying/listing and printing the list in reverse order? Make a program that will input an integer and then using loops, add items on an array/list one by one for the same number of times as that of the first inputted integer. Then, print out the array/list in reverse order, that is, starting from the last item on the array/list down to the first one, each in separated lines. Input 1. Size of the array 2. Elements of the array Output The first line will contain a message prompt to input the size of the array. The succeeding lines will contain message prompts to input the elements of the array. The next lines will contain the elements of the array in reversed order.

JAVA Problem Create a function that determines whether elements in an array can be re-arranged to form a consecutive list of numbers where each number appears exactly once. Examples cons([5, 1, 4, 3, 2]) → true // Can be re-arranged to form [1, 2, 3, 4, 5] cons([5, 1, 4, 3, 2, 8]) → false cons([5, 6, 7, 8, 9, 9]) → false //9 appears twice

dont give the same solution again .10 min left fast Array creation: There are various ways to create arrays in NumPy. O For example, you can create an array from a regular Python list or tuple using the array function. The type of the resulting array is deduced from the type of the elements in the sequences. O Often, the elements of an array are originally unknown, but its size is known. Hence, NumPy offers several functions to create arrays with initial placeholder content. These minimize the necessity of growing arrays, an expensive operation. For example: np.zeros, np.ones, np.full, np.empty, etc. O To create sequences of numbers, NumPy provides a function analogous to. range that returns arrays instead of lists. O arange: returns evenly spaced values within a given interval. step size is specified. O linspace: returns evenly spaced values within a given interval. num no. of elements are returned. O Reshaping array: We can use reshape method to reshape an array. Consider an array…

Imagine you want to use insertion sort for sorting a deck of cards, where the suits are ordered [Clubs, Spades, Diamonds, Hearts]. Thus, all the clubs will be ordered [Ace, 1, 2.., Queen, King], then all the Spades, etc. Create the pseudocode for this problem
Problem2: 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.
