在cpp中为了可移植性,string的长度是string::size_type,突然就想知道java允许的最大字符串长度为多少.看String的源码: public final class String 110 implements java.io.Serializable, Comparable<String>, CharSequence 111 { 112 /** The value is used for character storage. */ 1…
Given two strings s1 and s2, write a function to return true if s2 contains the permutation of s1. In other words, one of the first string's permutations is the substring of the second string. Example 1: Input:s1 = "ab" s2 = "eidbaooo"…
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]…
