Left Rotate Array by K Positions

Code

#include <stdio.h>

void rotate_left(int arr[], int n, int k) {
    int r;
    r = k%n;
    while(r){
        int i;
        int temp;
        temp = arr[0];
        int j = 4;
        int l = 0;
        while(j){
            arr[l] = arr[l+1];
            j--;
            l++;
        }
        arr[n-1] = temp;
        r--;
        
    }
}

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;
}
