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. [返回值]返回转换后的整型数:如果 str 不能转换成 int 或者 str 为空字符串,那么将返回 0.如果超出Integer的范围,将会返回I…

这道题是LeetCode里的第8道题. 题目要求: 请你来实现一个 atoi 函数,使其能将字符串转换成整数. 首先,该函数会根据需要丢弃无用的开头空格字符,直到寻找到第一个非空格的字符为止. 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. 该字符串除了有效的整数部分之后也可能会存在多余的字符,这些字符可以被忽略,它们对于函数不应该造成影响. 注意:假如该字…
