50. Reverse an Array Using Only Pointers

    // Your logic here
    int *left=ptr;
    int *right=ptr+(n-1);
    while(left<right)

            *right^=*left;
            *left^=*right;
        }
        left++;
        right--;
    }

int main() {
    int n;
    scanf("%d", &n);

    int arr[100];
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    reverse_array(arr, n);

    for (int i = 0; i < n; i++) {
