base64规则: * 字符串只可能包含A-Z,a-z,0-9,+,/,=字符* 字符串长度是4的倍数* =只会出现在字符串最后,可能没有或者一个等号或者两个等号 首先,C# 做上传文件的时候,需要替换掉这些字符: data:image/jpeg;base64, data:image/png;base64, data:image/gif;base64, if (str.Contains("base64,")) { str = str.Split("base64,")…

// ConsoleApplication10.cpp : 定义控制台应用程序的入口点. // #include "stdafx.h" #include <iostream> #include <vector> using namespace std; class Solution { public: /** * 返回git树上两点的最近分割点 * * @param matrix 接邻矩阵,表示git树,matrix[i][j] == '1' 当且仅当git树中…

Count the number of segments in a string, where a segment is defined to be a contiguous sequence of non-space characters. Please note that the string does not contain any non-printable characters. Example: Input: "Hello, my name is John" Output:…

We are to write the letters of a given string S, from left to right into lines. Each line has maximum width 100 units, and if writing a letter would cause the width of the line to exceed 100 units, it is written on the next line. We are given an arra…

To some string S, we will perform some replacement operations that replace groups of letters with new ones (not necessarily the same size). Each replacement operation has 3parameters: a starting index i, a source word x and a target word y.  The rule…

比如我将string作为CNN 文本处理输入: float [] input = new float[maxLength]; // 1 sentence by maxLenWords // int[] input = new int[batchSize * maxLength]; // 1 sentence by maxLenWords int i = 0; final int length = subdomain.length(); for (int offset = 0; offset <…

通常情况下,我们判断一个字符串中是否存在某值常常会用string.contains,其实判断一个字符串中存在某值的方法有很多种,最常用的就是前述所说的string.contains,相对来说比较常用的还有string.IndexOf和Regex.Match.直接上代码,后面在说些什么吧,通常情况下功能的实现最重要,作者的话,只对有心者有效. using System; using System.Collections.Generic; using System.Linq; using Syste…
