C Programming – HackerRank Solution | Reverse Array 1 |

(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

CODE:

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<math.h>

void calculate(int a[1000],int n,int k);
int main() {

   int n,a[1000],i,k;
    scanf("%d",&n);
    if(n>0 && npow(10,5))
            {
                printf("Invalid");
                exit(0);
            }
        }
            scanf("%d",&k);
            if(kn)
    {
        k=n;
    }
    j=k-1;
    while(k
