Left Rotate Array by K Positions

Code

#include <stdio.h>
void rotate_left(int arr[], int n, int k) {
     k = k % n; // Handle case when k > n
    if (k == 0) return;

    int temp[100];  // Temporary array

    // Copy rotated elements into temp
    for (int i = 0; i < n; i++) {
        temp[i] = arr[(i + k) % n];
    }

 // Copy back to original array
    for (int i = 0; i < n; i++) {
        arr[i] = temp[i];
    }
}

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;
}
