Dynamic programming, like the divide-and-conquer method, solves problems by combining the solutions to subproblems.
(“Programming” in this context refers to a tabular method, not to writing computer code.)
here what does the tabulor method mean? and why is it called like this?
------解决方案--------------------
动态规划其实最主要的是用一个table保存子问题的中间结果，运用递归实现
也许就是这个意思吧
