This article mainly introduces the Perl List::util module uses the example, this article gives the scanning matches the condition the list and takes out the first to satisfy the condition, asks for 1 to 1000 and, asks for a group of numbers maximum and the minimum value and so on the practical function code, needs the friend may refer to the next In Perl, there are modules dedicated to processing list data, such as the List::

In Perl, there are modules dedicated to processing list data, such as the List::util module, which is included in the standard library and provides a variety of efficient common list processing tools. Because of its use of C language to achieve, speed is generally very fast! Example 01 scans a list that meets the criteria and takes out the first qualifyingGeneral Practice: Copy Code code as follows: Use 5.010; My @names = QW (Wendy J

This problem is summarized as follows: Java. SQL. date is a subclass of Java. util. date. A thin package that encapsulates millisecond values allows JDBC to mark millisecond values as SQL date values. To be consistent with the definition of SQL date. SQL. the millisecond value encapsulated by the date instance must be specified by setting the time, minute, second, and millisecond to zero in a specific time zone related to the instance. The correspondi
