Algorithms

Given a string <code>s</code>, return the number of segments in the string.

A segment is defined to be a contiguous sequence of non-space characters.

&nbsp;
Example 1:

<pre>
Input: s = &quot;Hello, my name is John&quot;
Output: 5
Explanation: The five segments are [&quot;Hello,&quot;, &quot;my&quot;, &quot;name&quot;, &quot;is&quot;, &quot;John&quot;]
</pre>

Example 2:

<pre>
Input: s = &quot;Hello&quot;
Output: 1
</pre>

&nbsp;
Constraints:

<ul>
	<li><code>0 &lt;= s.length &lt;= 300</code></li>
	<li><code>s</code> consists of lowercase and uppercase English letters, digits, or one of the following characters <code>&quot;!@#$%^&amp;*()_+-=&#39;,.:&quot;</code>.</li>
	<li>The only space character in <code>s</code> is <code>&#39; &#39;</code>.</li>
</ul>

Number of Segments in a String

String

统计字符串中的单词个数，这里的单词指的是连续的不是空格的字符。

请注意，你可以假定字符串里不包括任何不可打印的字符。

示例:

<pre>输入: &quot;Hello, my name is John&quot;
输出: 5
解释: 这里的单词是指连续的不是空格的字符，所以 &quot;Hello,&quot; 算作 1 个单词。
</pre>
