- Multiply left and right array sum. Basic Accuracy: 54.29% Submissions: 12630 Points: 1 Pitsy needs help in the given task by her teacher. The task is to divide a array into two sub array (left and right) containing n/2 elements each and do the sum of the subarrays and then multiply both the subarrays. Example 1: â€arrow_forwardIN C PROGRAMMING LANGUAGE AND COMMENT EVERY LINE PLEASE SO I CAN UNDERSTAND EVERY STEP , The selection sort is one of several techniques for sorting an array. A selection sort compares every element of an array with all the other elements of the array and exchanges their values if they are out of order. After the first pass of a selection sort, the first array element is in the correct position; after the second pass the first two elements of the array are in the correct position, and so on. Thus, after each pass of a selection sort, the unsorted portion of the array contains one less element. Write and test a function that implements this sorting method.arrow_forwardWrite a program that reads the numbers and sorts them by using the Counting Sort algorithm and finally search a number from that array using Linear Search Algorithm. Input: 3 6 5 4 789 Search Item: 7 Output: Sorted Array: 3 4 5 6 789 Search item 7 is found.arrow_forwardPython Write a Python program that performs a linear (sequential) search. Define an array of 10 non-sequential numbers. Ask the user for a number, such as "Enter a number to be found:" Search the array for the user's number. If present, display "Successful search, the element is found at position " and its position. Otherwise, display "Number not found."arrow_forwardDesign a function: int search (float a[ ], int n, float x); The function searches in array a of size n for the item x. If x is found , its index is returned, otherwise -1 is returned. Design the main function also.arrow_forwardGiven an unsorted array write the pseudo code to sort it and find a specificelement xa. Find (array, x)// first sort the array// search for element x using binary searcharrow_forwardWhich methods/actions in the Sorted Array can be made significantly more efficient compared to the Unsorted Array? Why is this? In other words, what can be done in the Sorted Array implementation to radically improve the efficiency that can't be done in an Unsorted Array?arrow_forwardUse a one-dimensional array to solve the following problem. Read in 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, validate it and store it in the array only if it is not a duplicate of a number already read. After reading all the values, display only the unique values that the user entered. Provide for the “worst case” in which all 20 numbers are different. Use the smallest possible array to solve this problem.arrow_forwardThe binary search algorithm that follows may be used to search an array when the elements are in order. This algorithm is analogous to the following approach to finding a name in a telephone book. a. Open the book in the middle and look at the middle name on the page. b. b. If the middle name isn't the one, you're looking for, decide whether it comes before or after the name you want. c. Take the appropriate half of the section of the book you were looking in and repeat these steps until you land on the name. 1. Let the bottom be the subscript of the initial array element. 2. Let the top be the subscript of the last array element. 3. Let found be false. 4. Repeat as long as the bottom isn't greater than the top and the target has not been found. 5. Let middle be the subscript of the element halfway between bottom and top. 6. If the element in the middle is the target 7. Set found to true and index to middle. else if the element in the middle is larger than the target 8. Let the top be…arrow_forwardarrow_back_iosSEE MORE QUESTIONSarrow_forward_ios
