The result of each iteration is used as the starting values for the next. The values are checked during each iteration to see whether they have reached a critical "escape" condition, or "bailout". If that condition is reached, the calculation is stopped, the pixel is drawn, and the next x, y point is examined. For some starting values, escape ...
In languages which support first-class functions and currying, map may be partially applied to lift a function that works on only one value to an element-wise equivalent that works on an entire container; for example, map square is a Haskell function which squares each element of a list.
The iteration form of the Eiffel loop can also be used as a boolean expression when the keyword loop is replaced by either all (effecting universal quantification) or some (effecting existential quantification). This iteration is a boolean expression which is true if all items in my_list have counts greater than three:
An algorithm is fundamentally a set of rules or defined procedures that is typically designed and used to solve a specific problem or a broad set of problems.. Broadly, algorithms define process(es), sets of rules, or methodologies that are to be followed in calculations, data processing, data mining, pattern recognition, automated reasoning or other problem-solving operations.
it = iter (sequence) while True: try: value = it. next # in Python 2.x value = next (it) # in Python 3.x except StopIteration: break print (value) Any user-defined class can support standard iteration (either implicit or explicit) by defining an __iter__() method that returns an iterator object.
As a baseline algorithm, selection of the th smallest value in a collection of values can be performed by the following two steps: Sort the collection If the output of the sorting algorithm is an array , retrieve its k {\displaystyle k} th element; otherwise, scan the sorted sequence to find the k {\displaystyle k} th element.
The List Update or the List Access problem is a simple model used in the study of competitive analysis of online algorithms.Given a set of items in a list where the cost of accessing an item is proportional to its distance from the head of the list, e.g. a linked List, and a request sequence of accesses, the problem is to come up with a strategy of reordering the list so that the total cost of ...
In Fortran, a computed GOTO jumps to one of several labels in a list, based on the value of an expression. An example is goto (20,30,40) i . [ 44 ] The equivalent construct in C is the switch statement , and in newer Fortran a SELECT CASE construct is the recommended syntactical alternative. [ 45 ]
