数组中所有成对连续元素的绝对差

给定N个元素的整数数组。任务是打印所有成对连续元素的绝对差。

大小为N的数组的成对连续成对对(a [i]，a [i + 1])对于所有i，范围为0到N-2

例子：

Input: arr[] = {8, 5, 4, 3, 15, 20}
Output: 3, 1, 1, 12, 5

Input: arr[] = {5, 10, 15, 20}
Output: 5, 5, 5

方法：解决方案是遍历数组并计算并打印每对的绝对差(arr [i]，arr [i + 1])。

下面是上述方法的实现：

C++

// C++ program to print the absolute
// difference of the consecutive elements
#include 
using namespace std;
  
// Function to print pairwise absolute
// difference of consecutive elements
void pairwiseDifference(int arr[], int n)
{
    int diff;
    for (int i = 0; i < n - 1; i++) {
  
        // absolute difference between
        // consecutive numbers
        diff = abs(arr[i] - arr[i + 1]);
        cout << diff << " ";
    }
}
  
// Driver Code
int main()
{
    int arr[] = { 4, 10, 15, 5, 6 };
    int n = sizeof(arr) / sizeof(arr[0]);
  
    pairwiseDifference(arr, n);
  
    return 0;
}

Java

// Java program to print the absolute 
// difference of the consecutive elements 
  
class GFG{
// Function to print pairwise absolute 
// difference of consecutive elements 
static void pairwiseDifference(int arr[], int n) 
{ 
    int diff; 
    for (int i = 0; i < n - 1; i++) { 
  
        // absolute difference between 
        // consecutive numbers 
        diff = Math.abs(arr[i] - arr[i + 1]); 
        System.out.print(diff+" "); 
    } 
} 
  
// Driver Code 
public static void main(String[] args) 
{ 
    int arr[] = { 4, 10, 15, 5, 6 }; 
    int n = arr.length; 
  
    pairwiseDifference(arr, n); 
} 
}

Python 3

# Python 3 program to print the absolute
# difference of the consecutive elements
  
# Function to print pairwise absolute
# difference of consecutive elements
def pairwiseDifference(arr, n):
      
    for i in range(n - 1) :
  
        # absolute difference between
        # consecutive numbers
        diff = abs(arr[i] - arr[i + 1])
        print(diff , end = " ")
  
# Driver Code
if __name__=="__main__":
    arr = [ 4, 10, 15, 5, 6 ]
    n = len(arr)
  
    pairwiseDifference(arr, n)

C#

// C# program to print the absolute 
// difference of the consecutive elements 
using System;
  
class GFG{
// Function to print pairwise absolute 
// difference of consecutive elements 
static void pairwiseDifference(int []arr, int n) 
{ 
    int diff; 
    for (int i = 0; i < n - 1; i++) { 
  
        // absolute difference between 
        // consecutive numbers 
        diff = Math.Abs(arr[i] - arr[i + 1]); 
        Console.WriteLine(diff+" "); 
    } 
} 
  
// Driver Code 
public static void Main(String[] args) 
{ 
    int []arr = { 4, 10, 15, 5, 6 }; 
    int n = arr.Length; 
  
    pairwiseDifference(arr, n); 
} 
}

输出：

6 5 10 1
