首先看看判断字符串长度的几种方法(英文占1个字符,中文汉字占2个字符) 方法一: function strlen(str) { var len = 0; for (var i = 0; i < str.length; i++) { var c = str.charCodeAt(i); //单字节加1 if ((c >= 0x0001 && c <= 0x007e) || (0xff60 <= c && c <= 0xff9f)) { len++
We have two special characters. The first character can be represented by one bit 0. The second character can be represented by two bits (10 or 11). Now given a string represented by several bits. Return whether the last character must be a one-bit c
Given a string s , find the length of the longest substring t that contains at most 2 distinct characters. Example 1: Input: "eceba" Output: 3 Explanation: t is "ece" which its length is 3. Example 2: Input: "ccaabbb" Output
如下代码段是关于C#返回字符串的字节长度,一个中文算两个字符的代码. public static int GetLength(string str) { if (str.Length == 0) return 0; ASCIIEncoding ascii = new ASCIIEncoding(); int tempLen = 0; byte[] s = ascii.GetBytes(str); for (int i = 0; i < s.Length; i++) { if ((int)s[i]
