简介:String to Integer (atoi)Implement atoi to convert a string to an integer.【函数说明】atoi() 函数会扫描 str 字符串,跳过前面的空白字符(例如空格,tab缩进等),直到遇上数字或正负符号才开始做转换,而再遇到非数字或字符串结束时('\0')才结束转换,并将结果返回。
字符串转换整数 (atoi) 编程算法 当我们寻找到的第一个非空字符为正或者负号时,则将该符号与之后面尽可能多的连续数字组合起来,作为该整数的正负号;假如第一个非空字符是数字,则直接将其与之后连续的数字字符组合起来,形成整数。 韩旭051 2020/06/23 5450 leetcode: 8. String to Integer (atoi) 其他 ...
