Left Rotate Array by K Positions

Code

#include <stdio.h>

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