 - ### 动态规划（Dynamic Programming）
-    - This subject can be pretty difficult, as each DP soluble problem must be defined as a recursion relation, and coming up with it can be tricky.
+    - **注意** ：动态规划是门极为重要的技术，尽管其并未被 Google 提供的准备手册提及，但你可能会对寻求最佳解的方式有点疑问，所以我将其列入这份表单。
     - 这一部分会有点困难，每个可以用动态规划解决的问题都必须先定义出递推关系，要推导出来可能会有点棘手。
     - 我建议先阅读和学习足够多的动态规划的例子，以便对解决 DP 问题的一般模式有个扎实的理解。
