JAVA ARRAY MANIPULATION QUESTION: make a method called manipulator that takes a double array as parameter and modifies it. The method will modify the array then print the array. The method must modify the existing array, it CAN NOT create a different array as the solution. The manipulator method will be a void method.   Remember: To get an average of 2 digits you add them together then divide by 2. Average of x and y = (x+y)/2   Modifications the method will do: For every 2 consecutive elements in the array, both the elements are replaced by their average.  If the number of elements in an array is odd don't modify the last number of the array.   Basically, you find the average of 2 consecutive elements then replace both of the elements with that value. Examples: Array = {2.0,3.0} will be changed to {2.5,2.5} when passed to the manipulator method Array = {2.0,3.0,45} will be changed to {2.5,2.5,45} when passed to the manipulator method Array = {2.0,3.0,45,55} will be changed to…

python: numpy def purchases(transactions):    """    QUESTION 7    - A high-end store is trying to evaluate the total amount that customer's spend per transaction. They      want customers to spend anywhere between $130 and $150 on average.    - You need to determine whether the average number spent on each transaction per month is above, between, or      below the desired amount.    - Transactions is a numpy array containing a date, total amount earned each month, and total      number of transactions each month.    - Above: month's average amount spent per transaction > 150    - Within Range: 150 >= month's average amount spent per transaction >= 130    - Below: month's average amount spent per transaction < 130    - Return a numpy array with "Above", "Within Range" and "Below" for the average amount spent per transaction per month    - THIS MUST BE DONE IN ONE LINE    HINT: use np.where() and convert the type of each column to float     Args:        transactions…

Weight Statistics Write a program that monitors monthly weight loss each of 12 months into an array of doubles. The program should calculate and display the total weight loss for the year, the average monthly weight loss, and the months with the highest and lowest amounts.   Input Validation: Do not accept negative numbers for monthly weight loss.
