    It originally comes from CPL, in which equivalent syntax for e 1 ? e 2 : e 3 was e 1 → e 2, e 3. [1] [2] Although many ternary operators are possible, the conditional operator is so common, and other ternary operators so rare, that the conditional operator is commonly referred to as the ternary operator.

    en.wikipedia.org/wiki/Lookup_table

    In image processing, lookup tables are often called LUTs (or 3DLUT), and give an output value for each of a range of index values. One common LUT, called the colormap or palette , is used to determine the colors and intensity values with which a particular image will be displayed.

    en.wikipedia.org/wiki/PHP_syntax_and_semantics

    The purpose of the delimiting tags is to separate PHP code from non-PHP data (mainly HTML). Although rare in practice, PHP will execute code embedded in any file passed to its interpreter, including binary files such as PDF or JPEG files, or in server log files.

  9. Range tree - Wikipedia

    en.wikipedia.org/wiki/Range_tree

    A 1-dimensional range tree on a set of n points is a binary search tree, which can be constructed in (⁡) time. Range trees in higher dimensions are constructed recursively by constructing a balanced binary search tree on the first coordinate of the points, and then, for each vertex v in this tree, constructing a (d−1)-dimensional range tree on the points contained in the subtree of v.
