Problem statement:- Program to Print array in reverse order using recursion.
Data requirement:-
Input Data:-n, arr
Output Data:-arr
Output Data:-arr
Program in C
Here is the source code of the C Program to Print array in reverse order using recursion.
Code:
#include<stdio.h>
void ReverseArray(int arr[], int n)
{
int i;
if(n>0)
{
i=n-1;
printf("%d ",arr[i]);
ReverseArray(arr,i);
}
return;
}
int main()
{
int n,j;
printf("Enter your array size:");
scanf("%d",&n);
int arr[n];
printf("Enter the Array Element:");
for(j=0;j<n;j++)
{
scanf("%d",&arr[j]);
}
printf("After reversing Array Element Are:");
ReverseArray(arr,n);
return 0;
}
Enter your array size:5
Enter the Array Element:4 6 9 10 11
After reversing Array Element Are:11 10 9 6 4
Program in C++
Here is the source code of the C++ Program to Print array in reverse order using recursion.
Code:
#include<iostream>
using namespace std;
void ReverseArray(int arr[], int n)
{
int i;
if(n>0)
{
i=n-1;
cout<<arr[i]<<" ";
ReverseArray(arr,i);
}
return;
}
int main()
{
int n,i;
cout<<"Enter your array size:";
cin>>n;
int arr[n];
cout<<"Enter the Array Element:";
for(i=0;i<n;i++)
{
cin>>arr[i];
}
cout<<"After reversing Array Element Are:";
ReverseArray(arr,n);
return 0;
}
Enter your array size:6
Enter the Array Element:7 3 5 9 14 41
After reversing Array Element Are:41 14 9 5 3 7
Program in Java
Here is the source code of the Java Program to Print array in reverse order using recursion.
Code:
import java.util.Scanner;
public class PrintArrayReverseOrder {
static void ReverseArray(int arr[], int n)
{
int i;
if(n>0)
{
i=n-1;
System.out.print(arr[i]+" ");
ReverseArray(arr,i);
}
}
public static void main(String[] args) {
Scanner cs=new Scanner(System.in);
int n,i;
System.out.println("Enter your Array Size:");
n=cs.nextInt();
int arr[]=new int[n];
System.out.println("Enter the Array Element:");
for(i=0;i<n;i++)
{
arr[i]=cs.nextInt();
}
System.out.print("After reversing Array Element Are:");
ReverseArray(arr,n);
cs.close();
}
}
Enter your Array Size:
4
Enter the Array Element:
13 5 7 19
After reversing Array Element Are:19 7 5 13
Program in Python
Here is the source code of the Python program to Print array in reverse order using recursion.
Code:
def ReverseArray(arr,n):
if(n>0):
i=n-1
print(arr[i], end=" ")
ReverseArray(arr, i)
arr=[]
n = int(input("Enter the size of the array: "))
print("Enter the Element of the array:")
for i in range(0,n):
num = int(input())
arr.append(num)
print("After reversing Array Element Are:")
ReverseArray(arr,n)
Enter the size of the array: 3
Enter the Element of the array:
99
3
7
After reversing Array Element Are:
7 3 99
