M个范围切换操作后的二进制数组是什么？

Begin
   for each element e from index a to b, do
      toggle the e and place into arr at its position.
   done
End

#include <iostream>
using namespace std;
void toggleCommand(int arr[], int a, int b){
   for(int i = a; i <= b; i++){
      arr[i] ^= 1; //toggle each bit in range a to b
   }
}
void display(int arr[], int n){
   for(int i = 0; i<n; i++){
      cout << arr[i] << " ";
   }
   cout << endl;
}
int main() {
   int arr[] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
   int n = sizeof(arr)/sizeof(arr[0]);
   display(arr, n);
   toggleCommand(arr, 3, 6);
   toggleCommand(arr, 8, 10);
   toggleCommand(arr, 2, 7);
   display(arr, n);
}
