## 描述

Steven loves reading book on his phone. The book he reads now consists of N paragraphs and the i-th paragraph contains ai characters.

Steven wants to make the characters easier to read, so he decides to increase the font size of characters. But the size of Steven’s phone screen is limited. Its width is W and height is H. As a result, if the font size of characters is S then it can only show ⌊W / S⌋ characters in a line and ⌊H / S⌋ lines in a page. (⌊x⌋ is the largest integer no more than x)

So here’s the question, if Steven wants to control the number of pages no more than P, what’s the maximum font size he can set? Note that paragraphs must start in a new line and there is no empty line between paragraphs.

## 描述

1. 随机选择一个只包含大写字母的单词S作为密钥。
2. 将S中的所有字母J替换为字母I。
3. 将S中的字母依次填写进一个5x5的矩阵，按照从上到下、从左到右的顺序填充格子。填充过程中略过已经在密码表中的字母。
4. 将’A’-‘I’, ‘K’-‘Z’(除去J之外的所有大写字母)中没有出现在密码表中的大写字母按照字母表顺序填入矩阵剩余的格子中。

There’s lots of ways to be as a person, and some people express their deep appreciation in different ways.

But one of the ways that I believe people express their appreciation to the rest of humanity is to make something wonderful and put it out there.
And you never meet the people, you never shake their hands, you never hear their story or tell yours.

But somehow in the act of making something with a great deal of care and love, something’s transmitted there.And it’s a way of expressing to the rest of our species, our deep appreciation.
So we need to be true to who we are, and remember what’s really important to us.
