Suppose a Java method receives a List and reverses the order of the items it contains by removing each item from the front of the list, pushing each item onto a Stack, and after all items are pushed, popping the items from the stack and inserting each item at the end of the list. Assume push and pop are O(1). What is the expected Big-O running time if: a. If an ArrayList is passed. Explain your answer. b. If a Linked List is passed. Explain your answer.

Write a program that uses a two-dimensional array to store the highest and lowest temperatures for each month of the year. the program should output the average high, average low, and the highest and lowest temper- atures for the year. your program must consist of the following functions: a. function getdata: this function reads and stores data in the two- dimensional array. b. function averagehigh: this function calculates and returns the average high temperature for the year. c. function averagelow: this function calculates and returns the aver- age low temperature for the year. d. function indexhightemp: this function returns the index of the highest high temperature in the array. e. function indexlowtemp: this function retur
