Develop flowchart for this algorithm, The algorithm takes as input a search key and an array, output "key in arr: YES" or "key in arr: NO" Hint: use loop and two variables, one to store the starting index of the current search subarray and another to store the end of the current search subarray. These variables are often called start, end, low, high, etc. Let's call it L and H. In each iteration we search array from index L to H. Initially L is0 and H is the last index of the original array. In each iteration of the loop, we get middle index M and middle value. If the search key is smaller than the middle values, search 1st half of the array by setting

Please answer in matlab code.

Write a C++ program that reads a list of numbers from a file into an array, then uses that array to find the average of all the numbers, the average of the positive and negative numbers (0 is neither positive nor negative!), and the largest number. The point is to be able to store data in an array and do things with it Your program must contain at least the following four functions... read_list() This function will take as input parameters an array of integers and a string filename. It will open that file and read in numbers, storing them in the array, stopping at the end of the file. Remember that there are tricky issues with extra whitespace at the end of the file. You can assume the file contains only integers. The function will return the number of numbers that were read in.Note: In versions of Visual C++ pre-2010, when using the open function with a string argument, you must call the c_str() function on the string variable, such as:my_input_stream.open( filename.c_str() ) 2.…

The information about an array used in a program will be sorted in A. Symbol table B. Activation record C. Both (a) and (b) D. Dope vector
