The base case is whenever S1 or S2 is a zero-length string.
（基线条件（basecase）是S1或S2为长度为零的字符串的情形。
In this case, the LCS of S1 and S2 is clearly a zero-length string.
在这种情况下，S1和S2的LCS显然是长度为零的字符串。
If the argument is an empty sequence, fn: string (seq) will return a zero-length string, but the other function returns an empty sequence.
如果参数是空序列，fn：string (seq)将返回长度为零的字符串，另一个函数则返回空白序列。
A substring is zero or more contiguous string length units of input string.
子字符串是输入字符串的零个或多个相邻字符串长度单元。
A string whose length is greater than zero is always evaluated as True when resolved to a Boolean function, even if its value is the string 'false'.
长度大于0的字符串在解析为Boolean函数时，总是被判断为True，即使它的值是字符串'false '时亦是如此。
If the length of the string is zero, return a nonbreaking space; otherwise, return the seed and the name of the contestant.
如果字符串的长度为零，则返回一个未破坏的空间，否则，返回seed和竞争者的名称。
In addition to comparing the length and index values for equality, you must also check for either a null Number after parsing or an empty input string (" "or length of zero).
除了要比较长度和索引值是否相等之外，还必须检查是解析后的nullNumber还是一个空的输入字符串(或长度为0)。
However, the.net client de-serializes it into a zero length string instead of a null string.
然而，. NET客户端将其反序列化成长度为0的字符串而不是空的字符串。
The next section emits the traffic incident string to the display, if it has been received (which you know, because it has a non-zero length).
如果已经接收（您是可以判断的，因为它的长度是大于 0 的）到流量事件字符串，那么下一步就是显示它。
In general, one useful approach is to pass a length to the 'counted string' function one smaller than the size of the buffer and then explicitly assign zero to the last character in the buffer.
通常，一种有用的方法是，向“计数字符串”函数传递比缓冲区大小小一的长度，然后将零显式赋给缓冲区中的最后一个字符。
The string can be zero in length.
该字符串的长度可以是零。
