Left Rotate Array by K Positions

Code

#include <stdio.h>
void reverse(int *arr,int left,int right)
{
     while(left<right)
     {

       int temp=arr[left];
       arr[left]=arr[right];
       arr[right]=temp;
       left++;
       right--;

     }

}
void rotate_left(int arr[], int n, int k) {
    // Your logic here
    k=k%n;
    reverse(arr,0,k-1);
    reverse(arr,k,n-1);
    reverse(arr,0,n-1);

}

int main() {
    int n, k;
    scanf("%d %d", &n, &k);

    int arr[100];

    // Read array elements
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    // Rotate the array
    rotate_left(arr, n, k);

    // Print the rotated array
    for (int i = 0; i < n; i++) {
        printf("%d", arr[i]);
        if(i < n-1){
        	printf(" ");
        }
    }

    return 0;
}
