Write a program that uses a two-dimensional array to store the highest and lowest temperatures for each month of the year. Prompt the user for 12 months of highest and lowest. Write two methods : one to calculate and return the average high and one to calculate and return the average low of the year. These methods MUST be your original code. Your program should output all the values in the array and then output the average high and the average low.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 average 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 returns the index of the lowest low temperature in the array."

Our favorite program runs in 10 seconds on computer A, which has a 2 GHz clock. We are trying to help a computer designer build a computer, B, which will run this program in 6 seconds. The designer has determined that a substantial increase in the clock rate is possible, but this increase will affect the rest of the CPU design, causing computer B to require 1.2 times as many clock cycles as computer A for this program. What clock rate should we tell the designer to target?

My friend Leo wants to have an emergency plan for his final exams on University of Southern Algorithmville. He has N subjects to prepare for, and for each subject, his score is determined only by the time he spend on learning. It's not surprising that Leo found out he actually spent zero time on preparing before. At least he knows when he can start learning all of these subjects. For each subject i, there is a start time, si when he can get all materials ready to start learning. And there is also a ending time ei for each subject, when his learning materials expire and he can't learn anymore. We know that si and ei are integers, and Leo can only dedicate to a single subject within each time phase. Universtiy of Southern Algorithmville (USA), a student's total grade is the minimum grade among all subjects. Leo wants you to help him find out the best outcome. Given N subjects and their time intervals (si; ei ), design an algorithm to find out the maximum time possible for the least prepared subject. Prove the correctness of your algorithm. (Hint: It's not enough to use the network ow algorithm alone to determine the answer.)
