A message containing letters from A-Z is being encoded to numbers using the following mapping way: 'A' -> 1 'B' -> 2 ... 'Z' -> 26 Beyond that, now the encoded string can also contain the character '*', which can be treated as one of the numbers…

A message containing letters from A-Z is being encoded to numbers using the following mapping: 'A' -> 1 'B' -> 2 ... 'Z' -> 26 Given a non-empty string containing only digits, determine the total number of ways to decode it. Example 1: Input: &qu…

Medium! 题目描述: 一条包含字母 A-Z 的消息通过以下方式进行了编码: 'A' -> 1 'B' -> 2 ... 'Z' -> 26 给定一个只包含数字的非空字符串,请计算解码方法的总数. 示例 1: 输入: "12" 输出: 2 解释: 它可以解码为 "AB"(1 2)或者 "L"(12). 示例 2: 输入: "226" 输出: 3 解释: 它可以解码为 "BZ" (2 2…

随着移动端的发展,跨平台已成为通讯架构设计的重要考虑因素,PC.Android.IOS.WP等跨多平台间的数据通讯,必然要解决字符编码/解码的问题. 多字节字符集MBCS不是跨平台的首选字符集,面向跨平台.国际化的推荐字符集肯定是UNICODE. 写VC的人都知道,在以前VC++6.0中默认的字符集是多字节字符集,而VS2005及以后默认的字符集是Unicode,VS2013中默认不再对多字节字符串进行支持. 但对很多较早的服务端项目,依然使用的是多字节字符集,不过使用多字节字符集依然可以实现跨…
