Question

7. Write a python program to multiply the elements of two arrays in reverse
order and then sum them up. Assume that two arrays have the same size.
For example, if A = [2, 1, 8, 9] and B = [4, 2, 7, 12], then the result would be:
(2*12) + (1*7) + (8*2) + (9*4) = 24 + 7 + 16 + 36 = 83

8. Write the python code that takes in an array and prints out all pairs of
integers from the array whose sum is a prime number. For instance, if A =
[2, 9, 1, 8], the outcome would be (2, 1) , (2,9) and (9, 8).

Write a C program that reads an array of 10 integers from user. Your program should also read a key after reading array elements. Your program will decide whether or not the sum of two different array elements is the key. If that is the case, your code should print subscripts of those integers (If you find more than one case, print all of them). On the other hand, your program displays -1. Sample Input1: 23 41 7 9 12 44 56 21 45 10 16 Sample Output1: 23 Sample Input2: 77 23 -4 56 79 II 54 30 113 98 Sample Output2: 101 Sample Input3: 10 19 23 7 57 34 22 115 46 13 56 Sample Output3: 5 6
Write a program in c that create a 5-by-6 array. All elements in the array are random integer numbers between 1 and 100. Then, calculate the mean values of each column, and also find the minimums and maximums of each column. Print out the array, mean values, minimums,
Write a c program that declares and initializes two integer arrays x and y. They should have at least 5 elements. You are required to compute a dot product of these two arrays. For example one sample run output can look as follows:- intput array x:[-1 2 5 3 - 5 6] input array y:[-7 8 23 13 23 28] Dot product is:230.
Write a program that reads a 2D array of chars, checks, and corrects each char within this array, and print out the corrected 2D array. First the program will read the row count (rowCount) and column count (columnCount) of the 2D array, both as int values. Then, the chars constituting the 2D array will be read on a row-by-row basis. After reading the 2D array, the program will check and correct each char within the 2D array according to the rules below. This process MUST be done by using a void function by sending the appropriate cell of the 2D array with a call-by-reference fashion. If the row index is an even number, a char can only be a digit value. If the row index is an odd number, a char can only be an uppercase English letter. • Any incorrect value MUST be changed into Finally, the checked and corrected 2D array will be printed out to the screen. NOTE: Checking the correctness of a char and correcting it (if necessary) MUST be done in the function with a call-by-reference…
write a c++ program that takes array values as an input .for each array element, find the difference between that element and last array element and update the array. Take array size from user= 6 example: input array: 1, 4, 5, 6, 7, 2
Write a C++ program to copy the elements of an array into another by replacing every element with largest element to its right plus smallest element to its left. In case of first element, take the smallest to its left as zero and in case of last element, take largest element to its right as zero. For example, if the given array is: 1589635722, the modified array should be 9 10 10 8 8 8 8 3 31.
Write a program in C that create a 3-by-5 array. All elements in the array are random integer numbers between 1 and 100. Then, put all elements of the two-dimensional array into a one-dimensional array. Finally, calculate the mean value and the median value of 1-D array. Print out the 2-D array, original 1-D array, sorted 1-D array, and the mean value and the median value of 1-D array.
Write a C++ program that fills an integer array of size 10 with numbers. Next, the program fills the second array with the contents of the first array in reverse. Next, the program prints elements of both arrays. In addition, the program finds the minimum element from the first array and the maximum element from the second array. Sample input / output: Enter element (1): 45 Enter element (2): 23 Enter element (3): 16 Enter element (4): 38 Enter element (5): 94 Enter element (6): 75 Enter element (7): 58 Enter element (8): 61 Enter element (9): 80 Enter element (10): 69 Elements of first array: 45 23 16 38 94 75 58 61 80 69 Elements of second array: 69 80 61 58 75 94 38 16 23 45 The minimum element in the first array is: 16 The maximum element in the second array is: 94
Use Java programming language Given a 2-D array, print all flag numbers in the array in any order. A flag number is an element of the array such that it is the minimum element in its row and maximum in its column. Example 1: Input: matrix = [[3,7,8],[9,11,13],[15,16,17]] Output: [15] Explanation: 15 is the only flag number since it is the minimum in its row and the maximum in its column.
Given an array of size N-1 such that it only contains distinct integers in the range of 1 to N. Find the missing element. Example 1: Input:N = 5A[] = {1,2,3,5}Output: 4 Write the code for this problem in C++ and Python3
write a c++ program. where you have to work with a 2-d array such that each row can have different number of cols. e.g. row 0 has 2 cols, row 1 has 3 cols. Use dynamically allocated arrays. Input the number of rows from the user. then ask the user to input the number of cols of each row. Then ask the user to input the elements of each row. Finally display the sum of elements of each row.
2. In JAVA programming language write a program to input the elements of two integer arrays A1, A2 of size 10 and then print the absolute difference of the average of the arrays A1 and A2. The average of an array is the average of all the elements of the array.
