Leetcode 91. Decode Ways 解码方法(动态规划,字符串处理) 题目描述 一条报文包含字母A-Z,使用下面的字母-数字映射进行解码 'A' -> 1 'B' -> 2 ... 'Z' -> 26 给一串包含数字的加密报文,求有多少种解码方式 举个例子,已知报文"12",它可以解码为AB(1 2),也可以是L (12) 所以解码方式有2种. 测试样例 Input: "0" "121212" "1010…

An encoded string S is given.  To find and write the decodedstring to a tape, the encoded string is read one character at a time and the following steps are taken: If the character read is a letter, that letter is written onto the tape. If the charac…
