C Language Write a program to take two numerical lists of the same length ended with sentinel value and store  the lists in array X and array Y, each of which has 20 elements. Let N be the actual number of  data values in each list. Store the product of corresponding elements of array X and array Y into  third array Z of size 20. Display the square root of the sum of the items in array Z. Make up your  own data and be sure to test your program on at least one data set with number exactly 20 items.

In this lab, we will practice the use of arrays.   We will write a program that follows the steps below: Input 6 numbers from the user user inputs numbers one at a time Loop continuously until the exit condition below: ask the user to search for a query number if the query number is in the list: reports the first location of the query number in the list, change the number in that position to 0, show the updated list if the query number is not in the list: exit the loop   You must write at least one new function: findAndReplace(array1,...,query) – take in an array and query number as input (in addition to any other needed inputs); it will return the first location of the query number in the list (or -1 if it is not in the list) and will change the number at that location to 0.   You may receive the number inputs and print all outputs in int main if you wish.  You may report location based on 0-indexing or 1-indexing (but you need 0-indexing to access the array elements!).

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.

Python please...   Implement a function printIndex() that takes a list as a parameter, prompts the user to enter a whole number n, and prints the element in position Index[n]. If the list is empty ([]) or n is not a valid index into the list, the function will not print anything. Be careful to do the correct thing with negative indices. You should assume that the user will enter a whole number when prompted, and the function will crash if the user does not enter an integer. The function should not change the list passed as a parameter. Hint: Just because this involves a list does not mean that you need a loop to solve the problem. Think carefully about the right construct to use here. The following shows the function template, and several examples runs of the function (you must show all the examples with these values in your submission): Template def printIndex(lst):     replace with your docstring       newList = lst # ________________________     elementNum =…

The function interleave_lists in python takes two parameters, L1 and L2, both lists. Notice that the lists may have different lengths. The function accumulates a new list by appending alternating items from L1 and L2 until one list has been exhausted.  The remaining items from the other list are then appended to the end of the new list, and the new list is returned. For example, if L1 = ["hop", "skip", "jump", "rest"] and L2 = ["up", "down"], then the function would return the list: ["hop", "up", "skip", "down", "jump", "rest"]. HINT: Python has a built-in function min() which is helpful here.    Initialize accumulator variable newlist to be an empty list Set min_length = min(len(L1), len(L2)), the smaller of the two list lengths Use a for loop to iterate k over range(min_length) to do the first part of this function's work. On each iteration, append to newlist the item from index k in L1, and then append the item from index k in L2 (two appends on each iteration). AFTER the loop…

program- python Write a function called “missing”.  Ask the user for a series of integers from 1 to N.  Send that list to missing and have it return the list of what numbers are missing.   For example, if they enter 1 3 7 10, then you would call missing on that list which returns the list of missing numbers and then you can  let them know by printing out the list that they are missing 2 4 5 6 8 9.  Test it out on this and show it works. PLEASE USE SET SUBTRACTION

Write a program to sort an array of random elements using quicksort as follows: Sort the arrays using pivot as the first element of the array Sort the arrays using pivot as the median of the first, last, and middle elements of the array 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. 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. Calculate and display the CPU time for each of the preceding four steps. Example of the median of the first, last and middle elements: 1 2 3 4 5 6 7 8 0 (median of 1, 5, 0 is 1) 8 0 1 2 3 4 5 6 7 (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…

Question in image Please explain the algorithm with the answer. Python programming

1. Write a python program that combines two arrays of the same size one-in-a-row. For instance, if a=[1,2,3,4] and b=[5,6,7,8], the combined array should be [1,5,2,6,3,7,4,8].

Using c++ Contact list: Binary Search   A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Define and call the following function. The return value of FindContact is the index of the contact with the provided contact name. If the name is not found, the function should return -1 This function should use binary search. Modify the algorithm to output the count of how many comparisons using == with the contactName were performed during the search, before it returns the index (or -1). int FindContact(ContactInfo contacts[], int size, string contactName) Ex: If the input is: 3 Frank 867-5309 Joe…
