Given a string, return the length of the largest "block" in the string. A block is a run of adjacent chars that are the same.

Sure, I can help you with that. Here's a Python function that takes a string as input and returns the length of the largest block:

def largest_block(s):
    max_block_len = 0
    block_len = 1
    
    for i in range(1, len(s)):
        if s[i] == s[i-1]:
            block_len += 1
        else:
            max_block_len = max(max_block_len, block_len)
            block_len = 1
    
    return max(max_block_len, block_len)

Here's how you can use this function:

s = "abbcccdddd"
print(largest_block(s)) # Output: 4

In this example, the largest block in the string `s` is `"dddd"`, which has a length of 4.

输出The adjacent table of graph is：时多了->

非常抱歉，我不明白你的问题。请问你需要关于图的邻接表的输出吗？如果是的话，你可以这样输出：

假设有一个无向图，有5个顶点，边集合为：{(0,1),(0,2),(1,2),(2,3),(3,4)}，邻接表可以表示为：

0: 1 2
1: 0 2
2: 0 1 3
3: 2 4
4: 3

其中每一行表示一个顶点以及与该顶点相邻的顶点列表。

What is the purpose of the “rowspan” attribute of the “td” element?

The "rowspan" attribute of the "td" element in HTML is used to specify the number of rows that a cell should span. This attribute is useful when you want to merge two or more adjacent cells in a table into a single cell that spans multiple rows.

For example, if you have a table with three rows and three columns, and you want to merge the cells in the first column of the first two rows into a single cell, you can use the "rowspan" attribute. You would set the "rowspan" attribute of the first cell to "2", indicating that it should span two rows. This would cause the first two rows of the table to appear as if they have only two cells in the first column, instead of three.

Here is an example of how to use the "rowspan" attribute:

<table>
  <tr>
    <td rowspan="2">This cell spans two rows</td>
    <td>Cell 1</td>
    <td>Cell 2</td>
  </tr>
  <tr>
    <td>Cell 3</td>
    <td>Cell 4</td>
  </tr>
  <tr>
    <td>Cell 5</td>
    <td>Cell 6</td>
    <td>Cell 7</td>
  </tr>
</table>

In this example, the first cell spans two rows, so the first two rows of the table appear to have only two cells in the first column.
