我们在做项目时,可能会遇到这样的需求,比如判断,1,2,3,33,22,123, 中是否存在,3,. var str=",1,2,3,33,22,123,"; 一般有几种方式: 1.str.IndexOf(",3,")>=0 2.str.Contains(",3,") 有可能我们不用字符串而用List来存,判断list中是否存在3 var list = str.Split(',').ToList(); 3.list.Contains(&qu

写出将字符串中的数字转换为整型的方法,如:"as31d2v"->312,并写出相应的单元测试,输入超过int范围时提示不合法输入. public struct ConvertResult { public ConvertState State; public int Number; } public enum ConvertState { // 输入不合法 InValid = , // 输入合法 Valid = } public class StringHelper { publ
使用正则判断一个字符串中是否包含中文或者中文字符 代码实现如下: import java.util.regex.Matcher; import java.util.regex.Pattern; /** * Created by Miracle Luna on 2019/12/20 */ public class ChineseCheck { public static void main(String[] args) { String str = "Hello! <满江红>"
Consider the string s to be the infinite wraparound string of "abcdefghijklmnopqrstuvwxyz", so s will look like this: "...zabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcd....". Now we have another string p. Your job is to find
Write a function that takes a string as input and reverse only the vowels of a string. Example 1:Given s = "hello", return "holle". Example 2:Given s = "leetcode", return "leotcede". 这道题让我们翻转字符串中的元音字母,元音字母有五个a,e,i,o
Given an input string, reverse the string word by word. A word is defined as a sequence of non-space characters.The input string does not contain leading or trailing spaces and the words are always separated by a single space.For example,Given s = "t
Given an input string, reverse the string word by word. For example, Given s = "the sky is blue", return "blue is sky the". Update (2015-02-12): For C programmers: Try to solve it in-place in O(1) space. click to show clarification. Cl
1.1 Implement an algorithm to determine if a string has all unique characters. What if you cannot use additional data structure? 这道题让我们判断一个字符串中是否有重复的字符,要求不用特殊的数据结构,这里应该是指哈希表之类的不让用.像普通的整型数组应该还是能用的,这道题的小技巧就是用整型数组来代替哈希表,在之前Bitwise AND of Numbers Range 数
