1. This program will store integers entered by a user into an array. It then calls bubbleSort to sort the array. Study the code in bubbleSort to refresh your memory on Bubble Sort algorithm and answer the following questions a. Why do we need to pass the size of array to the function? b. Is the original array (the one being passed into the function) changed at the end of this function? c. Why do you think a new array (s_array) is needed to store the result of the sorted values (why not update the array as we sort)? Hint: look at what the main function does 2. Once you remember how Bubble Sort works, re-write the code so that you are accessing the array's content using pointer notations(*s_arr). i.e. you cannot use s arr[i] anymore. Comment out the original code so the algorithm won't be run twice. 3. After the array is sorted, the program will ask user to enter a key to search for in the sorted array. It will then call bSearch to perform a Binary Search on the array. Complete the bSearch function so that it implements Binary Search recursively (no loop!) You must use pointer notations here as well. Pay attention to what is written in main so your bSearch will return an appropriate value
