Description about program to reverse the array

Given an integer array of size N, write a program to reverse the array;

Sample input 1:

2 4 1 3

Sample output 1:

3 1 4 2

Sample input 2:

1 5 7 5 3

Sample output 2:

3 5 7 5 1

C Program to reverse the array

#include <stdio.h>

#include <limits.h>

void Reverse(int *arr, int n)

{

int temp;

for(int i = 0 ; i<n/2 ; i++)

{

temp = arr[i];

arr[i] = arr[n-1-i];

arr[n-1-i] = temp;

}

int main()

{

int n; scanf("%d",&n);

int arr[n];

for(int i = 0 ; i<n ; i++)

{

scanf("%d",&arr[i]);

}

Reverse(arr,n);

for(int i = 0 ; i<n ; i++)

{

printf("%d ",arr[i]);

}

return 0;

}

C++ Program to reverse the array

#include <bits/stdc++.h>

using namespace std;

int main()

{

int n; cin>>n;

int arr[n];

for(int i = 0 ; i<n ; i++)

{

cin>>arr[i];

}

reverse(arr,arr+n);

for(int i = 0 ; i<n ; i++)

{

cout<<arr[i]<<" ";

}

return 0;

}

JAVA Program to reverse the array

import java.util.*;

class Main

{

static void Reverse(int arr[], int n)

{

int temp;

for(int i = 0 ; i<n/2 ; i++)

{

temp = arr[i];

arr[i] = arr[n-1-i];

arr[n-1-i] = temp;

}

public static void main(String[] args) throws java.lang.Exception

{

Scanner sc = new Scanner(System.in);

int n = sc.nextInt();

int arr[] = new int[n];

for(int i = 0 ; i<n ; i++)

{

arr[i] = sc.nextInt();

}

Reverse(arr,n);

for(int i = 0 ; i<n ; i++)

{

System.out.print(arr[i] + " ");

}

PYTHON Program to reverse the array

n = int(input())

arr = list(map(int,input().split(' ')))

arr.reverse()

print(arr)
