Leetcode 65 Valid Number 字符串处理

由于老是更新简单题,我已经醉了,所以今天直接上一道通过率最低的题. 题意:判断字符串是否是一个合法的数字定义有符号的数字是(n),无符号的数字是(un),有符号的兼容无符号的合法的数字只有下列几种组合:(其中E可以大写) 有小数点和e (n).(un)e(n) .(un)e(n) (n).e(n) 仅仅有小数点的 (n).(un) .(un) (n). 仅仅有e的 (n)e(n) 没有e的 (n) 只要分别判断这上面的8种情况就能得到正确的答案更好的解法其实是一种叫做有限状态机的解法,下次…

[LeetCode] 65. Valid Number（多个标志位）

[思路]该题题干不是很明确,只能根据用例来理解什么样的字符串才是符合题意的,本题关键在于几个标志位的设立,将字符串分为几个部分,代码如下: class Solution { public: string trim(string s) { ; while(s[i]==' ') i ++; //开头处为空格或者Tab,则跳过 s=s.substr(i); i=s.size()-; while(s[i]==' ') i --; //结尾处为空格或者Tab,则跳过 s=s.substr(,i+); re…
