8是正数，8的补码就是原码，Integer.toBinaryString(8)，得到的二进制数字符串是 00000000 00000000 00000000 00001000，高位的0背省略，得到 1000，实际在内存中依旧是 32 位的二进制数

实现myAtoi(string s) 函数,该函数将字符串转换为 32 位有符号整数(类似于 C/C++ 的 atoi 函数)。 myAtoi(string s) 的算法如下: 读入并忽略任何前导空格。 检查下一个字符(如果还没有到达字符串的结尾)是否为'-'或'+'。如果是,就读入此字符。这将确定最终结果是负数还是正数。如果两者都不存在,则假设...
