As the head/tail breaks method can be used iteratively to obtain head parts of a data set, this method actually captures the underlying hierarchy of the data set. For example, if we divide the array (19, 8, 7, 6, 2, 1, 1, 1, 0) with the head/tail breaks method, we can get two head parts, i.e., the first head part (19, 8, 7, 6) and the second ...

A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java. However, there are some ...
Even if it were to allocate the head node before duplicating the rest, it would still need to plug in the result of the recursive call into the next field after the call. [a] So the function is almost tail recursive. Warren's method pushes the responsibility of filling the next field into the recursive call itself, which thus becomes tail call.
head -n 20 filename. This displays the first 5 lines of all files starting with foo: head -n 5 foo* Most versions [citation needed] allow omitting n and instead directly specifying the number: -5. GNU head allows negative arguments for the -n option, meaning to print all but the last - argument value counted - lines of each input file.-c bytes
A queue is an example of a linear data structure, or more abstractly a sequential collection. Queues are common in computer programs, where they are implemented as data structures coupled with access routines, as an abstract data structure or in object-oriented languages as classes.
compiles down to the optimal Python code just-in-time; optional ahead-of-time template compilation; easy to debug (for example, line numbers of exceptions directly point to the correct line in the template) configurable syntax; Jinja, like Smarty, also ships with an easy-to-use filter system similar to the Unix pipeline.
[3]: 288 For example, iteration over a directory structure could be implemented by a function class instead of more conventional loop pattern. This would allow deriving various useful information from directories content by implementing a visitor functionality for every item while reusing the iteration code.
