You are given an array of N non-negative integers: A1, A2, ..., AN. An alternating subsequence is a subsequence in which the indices of any two consecutive elements differ by exactly two in the original array. That is, if Ai1, Ai2, ..., Aik is some subsequence, then for it to be an alternating subsequence, (i2 - i1 = 2), (i3 - i2 = 2), and so on should all hold true. Among all alternating subsequences, find the one which has maximum sum of elements, and output that sum.
Modify the following program to check for reasonable inputs (or reject un-reasonable ones). For example, a negative GPA or test score, or a GPA of 10 or a test score of more than 100.
using System;
namespace Admit
{
class Program
{
public static void Main(string[] args)
{
float avg;
int score;
Console.WriteLine("Grade point average: ");
avg = float.Parse(Console.ReadLine(), System.Globalization.CultureInfo.InvariantCulture); //decimal mark is "."
Console.WriteLine("Admission test score: ");
score = int.Parse(Console.ReadLine());
if ((avg >= 3) && (score >= 60) || (avg < 3) && (score >= 80))
Console.Write("Accept");
else
Console.Write("Reject");
Console.ReadKey(true);
}

A milk carton can hold 3.78 liters of milk. Each morning, a dairy farm ships cartons of milk to a local grocery store. The cost of producing one liter of milk is 0.38, and the profit of each carton of milk is 0.27.
Write a program that does the following:
a. Prompts the user to enter the total amount of milk produced in the morning
b. Outputs the number of milk cartons needed to hold milk (Round your answer to the nearest integer.)
c. Outputs the cost of producing milk
d. Outputs the profit for producing milk

A force F=100N points 300 with respects to the x-axis. The force acts on an object of mass 5kg.
a. what is the magnitude and direction of the acceleration of that object ? [3+2 marks]
b. what are the magnitudes of the x-components of the force and the acceleration (Fx and ax)?
An egg distribution company uses different sizes of packings for eggs, that is, 30 eggs packing, 24 eggs packing, 18 eggs packing, 12 eggs packing and 6 eggs packing. Write a program which prompts user to enter total number of eggs (input validation is always must) to be packed and then calculate how many packings of each size will be possible. Also tell if there will be any eggs left to be packed.
