LIS

51nod is good.

Edit distance

I started to learn "Edit distance" though I still can't understand "LCS" enough.We will always encounter some trenches that cannot be crossed. At this time, we need to go around and wait until we are strong enough to solve this problem. This will never be the reason for us to stop.

LCS

DP is too difficult for me.

A Basic Greedy

Greedy is a exacting method for programming,though it is not so good for us.

Basic Dynamic programming

Yesterday a senior teach us about dynamic planning and i'd like to recorded this basic question.

Long Number

Oh,CF's charm is too strong,especially div3.

The game I played in the NOWCODER.COM a few days ago, the first time I met the “union-find” problem, it was solved with the help of the seniors. I have digested it in the past few days, or I wrote it on the blog first.

Hangman Judge

在学长的指点下，买了一本紫薯来啃，前两章食用感觉还不错。。。到了第三章例题虽然可以看懂，习题已经做不出来了。到了第四章，例题都有点看不懂了🤢！！！用了接近一下午的时间做出来一道例题，登到这里记录一下，顺便夸夸自己。

矩形面积并

这道题在我刚刚接触算法的时候就遇见过。。。当时暴力解了出来。第二次遇见没做出来，学长教了我一下，我又没仔细学。。昨天校赛的时候再次遇见。凉透了。把学长传下来的代码自己写一遍再贴在这里，时常告诫自己！

今天跟着众多大佬学长去了郑轻参加天梯赛，显然我拖了大佬后腿，一拖九了解一下，吓得我快来补题先。
