<p>给定字符串 <strong>s</strong> 和 <strong>t</strong> ，判断 <strong>s</strong> 是否为 <strong>t</strong> 的子序列。</p>
|
|||
|
|
|
|||
|
|
<p>字符串的一个子序列是原始字符串删除一些（也可以不删除）字符而不改变剩余字符相对位置形成的新字符串。（例如，<code>"ace"</code>是<code>"abcde"</code>的一个子序列，而<code>"aec"</code>不是）。</p>

|
|
|
|||
|
|
<p>如果有大量输入的 S，称作 S1, S2, ... , Sk 其中 k >= 10亿，你需要依次检查它们是否为 T 的子序列。在这种情况下，你会怎样改变代码？</p>
