Leetcode: Decode Ways

难度：90. 非常不错的一道一维DP题目，参考了网上的做法。看到这种求数量的，我们很容易想到动态规划来存储前面信息，然后迭代得到最后结果。我们维护的量res[i]是表示前i个数字有多少种解析的方式，接下来来想想递归式，有两种方式：第一种新加进来的数字不然就是自己比较表示一个字符，那么解析的方式有r

LeetCode Decode Ways

有点意思的题目。用动态规划能够O(n)求解出来：a[i]代表子字符串string(0,i)的可能解码方式，a[i] = {a[i-1] or a[i-1]+a[i-2]}. 意思是假设string(i)不为0，至少a[i] == a[i-1]，即一种解码方法是string{0,.....(i-1)}

91. Decode Ways

这道题想到了用dp做，其实最后还是在缝缝补补，不过现在思路清晰一点了，这道题的难点就是0的decode 思路：首先要想明白的是，开头是0或者有连续两个0，那么decode就会失败，即return 0，想明白这点剩下的就简单了，想到用dp做的原因是，我们把假设string 是121，想象成一个一个放入，一开始容器只有一个1，之后再放入2，那么ways的增加即是新放入的2与原来的way decode中
