For example, reverse :: List a -> List a, which reverses a list, is a natural transformation, as is flattenInorder :: Tree a -> List a, which flattens a tree from left to right, and even sortBy :: (a -> a -> Bool) -> List a -> List a, which sorts a list based on a provided comparison function.
Object REXX is a high-level, general-purpose, interpreted, object-oriented (class-based) programming language.Today it is generally referred to as ooRexx (short for “Open Object Rexx”), which is the maintained and direct open-source successor to Object REXX.
If you are using more than one drop down list on the same page this parameter is very important. The Id parameter for each list should be different and unique (if using more than one on the same page). Hence the for example {{Drop down list|Name=text1|id=IdName1|Value1=a|Value2=b|Value3=c}}
A drop-down list or drop-down menu or drop menu, with generic entries. A drop-down list (DDL), drop-down menu or just drop-down [1] – also known as a drop menu, pull-down list, picklist – is a graphical control element, similar to a list box, that allows the user to choose one value from a list either by clicking or hovering over the menu.
The most frequently used general-purpose implementation of an associative array is with a hash table: an array combined with a hash function that separates each key into a separate "bucket" of the array. The basic idea behind a hash table is that accessing an element of an array via its index is a simple, constant-time operation.

Multiple numerical tail elements can be used to provide the effect of a multi-dimensional array. Features similar to the compound variable are found in other languages including associative arrays in AWK, hashes in Perl and hash tables in Java, dynamic objects in JavaScript. Most of these languages provide a mechanism to iterate over the keys ...
