Problem
An array is a series of elements of the same type placed in contiguous memory locations that can be individually referenced by adding an index to a unique identifier.
Declaration:
int arr[10]; //Declares an array named arr of size 10, i.e; you can store 10 integers.
Accessing elements of an array:
Indexing in arrays starts from 0.So the first element is stored at arr[0],the second element at arr[1]...arr[9]
You’ll be given an array of N integers and you have to print the integers in the reverse order.
Input Format
The first line of the input contains N, where N is the number of integers. The next line contains N integers separated by a space.
Constraints
- 1<= N <= 1000
- 1<= Ai <= 10000 where Ai is the ith integer in the array.
Output Format
Print the N integers of the array in the reverse order in a single line separated by a space.
Sample Input
4 1 4 3 2
Sample Output
2 3 4 1

Code:
#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
#define MAX 10000
using namespace std;
int main()
{
/* Enter your code here. Read input from STDIN. Print output to STDOUT */
int a[MAX], N,i;
cin>>N;
for(i=1;i<=N;i++)
{
cin>>a[i];
}
for(i=0;i<N;i++)
{
cout<<a[N-i]<<" ";
}
return 0;
}
