How to use binary search to find the first non-null element in an array?
如何使用二进制搜索来找到数组中第一个非空元素呢?
Suppose a .NET client sends out an array with a null element as shown in the code in Listing 9.
假设.NET客户端发出含有空元素的数组,代码如 清单 9所示。
More formally, sets contain no pair of elements e1 and e2 such that e1.equals (e2), and at most one null element.
更准确地说,set不包含成对的e1和e2元素,因此如果e1 .equals (e2),那么最多包含一个null元素。
In this case, by default, the value of the new element is deemed to represent a value of NULL.
在这种情况下,新元素的值默认表示null值。
If there is no year element, then the call will return null.
如果没有year元素,则调用返回一个空值。
The returned ModelElement is the model element that is being replaced by the newly added model element, or NULL if no element is being replaced.
返回的ModelElement是新添加的模型元素所替换的模型元素,如果没有替换任何元素,则为NULL。
But as we hope we've shown in the table, that really represents an array with a single element whose value is null, not a null array.
但是,正如我们希望的,在表中已经显示,它真正表示的是含有单一元素的数组,元素的值为“零”(null),而不是一个“零”(null)数组。
The SQL query USES the stored procedures to create one XML listing element per row of data returned, passing in null as the column to obtain its value from because its value is its subelements.
SQL查询使用存储过程为每行返回数据创建一个xml列表元素,同时传递null作为列以获取值,因为它的值就是它的子元素。
Path location — Returns an element or null if it doesn't exist in a non-modifiable tree.
路径位置——返回一个元素,如果不可修改的树中不存在该元素,则返回null。
The String element, s[1], is assigned a null value.
这里的String元素s[1]被赋为空值。
In the "key" element, the default values for "not-null" and "update" are false and true, respectively. The above code shows them for the purpose of clarity.
在“key”元素中,“not -null”和“update”对应的默认值是false和true,上述代码为了明确这些取值,将它们写了出来。
The regmatch(re, text) function compares the regular expression to the text, yielding either Null for no matches or an array of pairs of integers (a two-element array).
regmatch(re,text)函数将比较正则表达式和文本,如果没有匹配的话就生成Null 值,否则生成一个由成对整数组成的数组(双元素数组)。
The annotated element must not be null. Accepts any type.
带注释的元素不能为空。接受任何类型。
When you specify the element directive to retrieve element-centric XML, if the column has a NULL value, the corresponding element is not generated by the EXPLICIT mode.
当指定ELEMENT指令检索以元素为中心的XML时,如果列具有NULL值,则EXPLICIT模式将不生成相应的元素。
Output: For each test case, the element values of its child nodes are output in the preceding order. If null output null.
输出:对应每个测试案例,按照前序输出其孩子节点的元素值。若为空输出NULL。
The annotated element must not be null.
带注释的元素不能为空。
