Hello Programmers, In this post, you will know how to solve the Arrays Introduction in C++ HackerRank Solution. This problem is a part of the HackerRank C++ Programming Series.
One more thing to add, don’t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.
Arrays Introduction in C++ HackerRank Solutions
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
