Single pass macroprocessor

You can help by adding to it. February Disadvantages[ edit ] One-pass compilers are unable to generate as efficient programs as multi-pass compilers due to the limited scope of available information. Many effective compiler optimizations require multiple passes over a basic blockloop especially nested loopssubroutine, or entire module.

January Learn how and when to remove this template message In computing, a one-pass algorithm is a streaming algorithm which reads its input exactly once, in order, without unbounded buffering.

A one-pass algorithm generally requires O n see 'big O' notation time and less than O n storage typically O 1where n is the size of the input.

Single pass macroprocessor

Basically one-pass algorithm operates as follows: Count the number of elements. Find the nth element or report that the list has fewer than n elements.

Find the nth element from the end or report that the list has fewer than n elements. Given a list of numbers: Find the k largest or smallest elements, k given in advance. Find the summeanvariance and standard deviation of the elements of the list.

Given a list of symbols from an alphabet of k symbols, given in advance.

Question Bank

Count the number of times each symbol appears in the input. Find the most or least frequent elements. Sort the list according to some order on the symbols possible since the number of symbols is limited.

Find the maximum gap between two appearances of a given symbol. Example problems not solvable by one-pass algorithms[ edit ] Given any list as an input: Find the middle element of the list.

ALGORITHM: 1. Get the statement from the input file 2. If the statement has the directive “MACRO”, then the number of macro “n” will beAuthor: Praveen. In computing, a one-pass algorithm is a streaming algorithm which reads its input exactly once, in order, without unbounded buffering.

A one-pass algorithm generally requires O(n) (see 'big O' notation) time and less than O(n) storage (typically O(1)), where n is the size of the input.
