Write a function that returns the reverse of the input array.
Input specification:
Input1: an array of numbers
Input2: length of the array(input1)
Output Specification:
Return an array in reverse order.
Example 1:
Input 1: {1,2,3}
Input 2: 3
Output: {3,2,1}
Explanation:
The reverse of the array {1,2,3} will be {3,2,1}
Example 2:
Input 1: {4,6,7,2}
Input 2: 4
Output: {2,7,6,4}
Explanation:
The reverse of the array {4,6,7,2} will be {2,7,6,4}

arr = list(map(int, input().split()))
l=int(input())
a = arr[::-1]
for i in a:
print(i,end=' ')

#include <bits/stdc++.h>
#include <iostream>
using namespace std;
int main()
{
int input;
vector<int> arr;
while(cin >> input)
arr.push_back(input);
for(int i=arr.size()-2;i>=0;i--)
cout << arr[i] << " ";
return 0;
}Output:
3 2 1 4 5
5
5 4 1 2 3
