**(HackerRank) Write a Modular C Programming code to solve Reverse Array 1 , Given an array of ‘N’ elements reverse an array with the group size of ‘K’.**

Given an array of ‘N’ elements reverse an array with the group size of ‘K’.

**Input Format**

First Line contains ‘N’ size of an array followed by N array elements in second line.

Third Line contains ‘K’, the reversal factor

**Constraints**

N>0 and N<=10^5

10^-5 <= a[i]<= 10^5

K>0

**Output Format**

Display the rotated array seperated by a space

**Sample Input 0**

```
-1
```

**Sample Output 0**

```
Invalid
```

**Sample Input 1**

```
8
1 2 3 4 5 6 7 8
5
```

**Sample Output 1**

```
5 4 3 2 1 6 7 8
```

**Explanation 1**

```
Since the reversal factor is 5, reverse the first five elements of the array, the array becomes 5 4 3 2 1, there are three remaining elements 6 7 and 8, and there are three elements less than K (5) so we don't reverse them
```

**Sample Input 2**

```
5
1 2 3 4 5
6
```

**Sample Output 2**

```
5 4 3 2 1
```

**Explanation 2**

`If the K, is greater than N, then reverse the complete array`
