Left Rotate Array by K Positions

Code

#include <stdio.h>
void revers(int arr[],int start,int end)
{
    while(start < end)
        {
            arr[start]^=arr[end]^=arr[start]^=arr[end];
            start++;
            end--;
        }
}
void rotate_left(int arr[], int n, int k) {
    k = k%n;
    revers(arr,0,k-1);
    revers(arr,k,n-1);
    revers(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;
}
