 bit position of the tick. To find the mask, we simply calculate `2**bit_pos` (equivalent of `1 << bit_pos`):
 ```python
 mask = 2**bit_pos # or 1 << bit_pos

 Next, to flip a flag, we apply the mask to the tick's word via bitwise XOR:
 ```python
 word = (2**256) - 1 # set word to all ones
-print(bin(word ^ mask))                                                   ↓ here
