# Arrays Introduction

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.

For arrays of a known size, in this case, use the following declaration:

```
int arr[10]; //Declares an array named arr of size 10, i.e, you can
store 10 integers.
```

**Note** Unlike C, C++ allows dynamic allocation of arrays at runtime without special calls like malloc(). If , `int arr[n]`

will create an array with space for 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] and so on through arr[9].
```

You will be given an array of integers and you have to print the integers in the reverse order.

**Input Format**

The first line of the input contains ,where is the number of integers.The next line contains space-separated integers.

**Constraints**

, where is the integer in the array.

**Output Format**

Print the integers of the array in the reverse order, space-separated on a single line.

**Sample Input**

```
4
1 4 3 2
```

**Sample Output**

```
2 3 4 1
```
