course, the code is a bug, if there is no pattern string in the input text string, it may not show, I did not take this into account. Need to improve, but in order to understand the algorithm itself, I will not modify too much, because the above code is already relatively clear. (OK, actually I am lazy, write code in the middle of the night, not easy AH)I think it would be a little clearer if I understood the above method, and thought, and then went to see the guide of the calculation. But the
