Left Rotate Array by K Positions

Code

#include <stdio.h>

void rotate_left(int arr[], int n, int k) {
    
    k = k % n; 
    
    int l[k];    
    int m = 0;
    for(int j = 0; j < k; j++) {
        l[j] = arr[j];
    }
    for(int i = k; i < n; i++) {
        arr[m] = arr[i];
        m++;
    }
    for(int i = 0; i < k; i++) {
        arr[m] = l[i];
        m++;
    }
}

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;
}
