Question

Create in C#

Write a method called MaximumDiffrence that accepts an integer array as a parameter and return the maximum difference between adjacent values in the array, where the gap is defined as the absolute value of the difference between the 2 adjacent values.

Example: if the array contains {5, 7, 4, 9, 6, 12, 8} so

The first gap is (5,7)=-2 and the absolute value is 2

The second gap is (7,4)=3

Third gap is (4,9) = -5 its absolute value is 5

Fourth gap is (9,6) = 3

Fifth gap is (6,12) = 6

Sixth gap is (12, 8) = 4

The method should return 6, the max absolute difference If the array has just 2 or less elements, then it should return 0

Answer 1

using System.IO;
using System;

class Program
{
public static int maxDiff(int[] Array, int arraySize)
{
int maxDiff = Array[1] - Array[0];
int i, j, diff;
if( arraySize<=2) // checking if elements are equal to or less than 2.
{
return 0;
}
for (i = 0; i < arraySize; i++)
{
j=i+1;
diff = Math.Abs(Array[j] - Array[i]);
if (diff > maxDiff)
maxDiff = diff;
if (i!=arraySize-1) {
Console.Write(" {0} gap difference ({1},{2}): {3}", i+1, Array[i], Array[j], diff);
}
}
Console.Write(" ");
  
return maxDiff;
}
  
static void Main()
{
int[] Array = new int[100];
int n,i;
Console.WriteLine("Enter the number of elements: ");
n = Convert.ToInt32(Console.ReadLine());
for(i=0; i<n; i++)
{
   Console.Write("Element {0} : ",i+1);
   Array[i] = Convert.ToInt32(Console.ReadLine());        
}
  
Console.Write(" Elements in array are: ");
Console.Write(" ");
for(i=0; i<n; i++)
{
Console.Write("{0} ", Array[i]);
}
  
Console.Write(" Maximum difference is " +
maxDiff(Array, n));
  
}
}

Output

1. Elements less than or equal to 2

2. More than 2 elements
