Day 7: array|| hackerrank || 30 days of code || programming_info

Objective
Today, we're learning about the Array data structure. Check out the Tutorial tab for learning materials and an instructional video!

Task
Given an array, , of  integers, print 's elements in reverse order as a single line of space-separated numbers.

Input Format

The first line contains an integer,  (the size of our array).
The second line contains  space-separated integers describing array 's elements.

Constraints

• , where  is the  integer in the array.

Output Format

Print the elements of array  in reverse order as a single line of space-separated numbers.

Sample Input

4
1 4 3 2

Sample Output

2 3 4 1

Solution using C language:

#include <cmath>

#include <cstdio>

#include <vector>

#include <iostream>

#include <algorithm>

using namespace std;

int main() {

    /* Enter your code here. Read input from STDIN. Print output to STDOUT */ 

     int n,a[1000],i,j,t;

      cin>>n;

      for(i=0;i<n;i++)

        {

            cin>>a[i];

        }

     for(j=0;j<n;j++);

        for(i=0;i<(j/2);i++)

                {

                    t=a[i];

                    a[i]=a[n-i-1];

                    a[n-i-1]=t;

                }

    for(i=0;i<n;i++)

        {

            cout<<a[i]<<" ";

        }

    return 0;

}
