Special binary strings are binary strings with the following two properties: The number of 0's is equal to the number of 1's. Every prefix of the binary string has at least as many 1's as 0's. Given a special string S, a move consists of choosing two
Given two binary strings, return their sum (also a binary string). For example,a ="11"b ="1"Return"100". 思路很简单,先把短的字符串补齐,然后逐位相加. string addBinary(string a, string b) { int length = max(a.size(), b.size()); , ' '); '; while (l
本例子的目的在于测试往oracle数据库中插入blob字段 //以下代码源于:https://www.cnblogs.com/ywlx/p/4544179.html public static String getImgStr(String imgFile){ //将图片文件转化为字节数组字符串,并对其进行Base64编码处理 InputStream in = null; byte[] data = null; //读取图片字节数组 try { in = new FileInputStream(
一.查看编码 1.查看oracle数据库编码 命令:select * from nls_database_parameters where parameter ='NLS_CHARACTERSET'; 执行结果: 查询的数据来源props$,这个代表的是数据库字符集. 2.查看oracle客户端编码 命令:select * from nls_instance_parameters where parameter='NLS_LANGUAGE'; 执行结果: 查询的数据来源vparameter,这个
