2. 从前往后遍历,发现空格,i++ 3. 若有符号,存储sign(flag) 4. 字符串转整数,result = result * 10 + ord(str[i]) - ord('0'),如果溢出直接返回MAX或MIN 代码 class Solution(object): def myAtoi(self, str): """ :type str: str :rtype: int """ INT_MAX = 2147483647 INT_MIN = -2...
If no valid conversion could be performed, a zero value is returned. Note: Only the space character ' ' is considered as whitespace character. Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−231,231−1−231,231−1...
