Answer to the question

Idea: the picture above is the automata that can be sorted out on this topic, and the difficulty of this topic is how to sort out the state transition diagram of the automaton. After combing out, the relevant rules can be written into the code according to the state transfer. The following code is written before looking at the official problem, so it will be slightly different from the picture above. The official code can be checked on the LeetCode website. Class Solution: def myAtoi (self, str: str)-> int: str = str.strip () if len (str) = = 0: return 0 yellows'if str [0] .isometric (): y=y+str [0] for i in range (1) Len (str): if str[ I] .isometric (): y=y+str [I] else: break elif (str [0] = ='-'or str [0] = ='+') and 10: if 2 cycles 31-1 > = int (y) > =-2 cycles 31: return int ( Y) elif int (y) > 2 / 2 / 31-1: return 2 / 31 / 1 else: return-2 / 31 else: return 0
