"""
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：假如该字符串中的第一个非空格字符不是一个有效整数字符、字符串为空或字符串仅包含空白字符时，则你的函数不需要进行转换。
在任何情况下，若函数不能进行有效的转换时，请返回 0。
