Output: A sorted list L1 containing those integers present in L Writing a pseudocode has no restriction of styles and its only objective is to describe the high level steps of algorithm in a much realistic manner in natural language.įor example, following is an algorithm for Insertion Sort. On the other hand, pseudocode is an informal and (often rudimentary) human readable description of an algorithm leaving many granular details of it. Generally, the word "algorithm" can be used to describe any high level task in computer science. Difference between Algorithm and PseudocodeĪn algorithm is a formal definition with some specific characteristics that describes a process, which could be executed by a Turing-complete computer machine to perform a specific task. The running time can be estimated in a more general manner by using Pseudocode to represent the algorithm as a set of fundamental operations which can then be counted. Pseudocode gives a high-level description of an algorithm without the ambiguity associated with plain text but also without the need to know the syntax of a particular programming language. Algorithms should not run for infinity, i.e., an algorithm must end at some point The main characteristics of algorithms are as follows −Īlgorithms should have explicitly defined set of inputs and outputsĪlgorithms are well-ordered with unambiguous operationsĪlgorithms halt in a finite amount of time. Checking the correctness of an Algorithm.
The following steps are involved in solving computational problems. If we require an algorithm to run in lesser time, we have to invest in more memory and if we require an algorithm to run with lesser memory, we need to have more time. However, one has to keep in mind that both time consumption and memory usage cannot be optimized simultaneously. Some of them can be efficient with respect to time consumption, whereas other approaches may be memory efficient.
To solve a problem, different approaches can be followed. The important aspects of algorithm design include creating an efficient algorithm to solve a problem in an efficient way using minimum time and space. If we have an algorithm for a specific problem, then we can implement it in any programming language, meaning that the algorithm is independent from any programming languages. An algorithm is an efficient method that can be expressed within finite amount of time and space.Īn algorithm is the best way to represent the solution of a particular problem in a very simple and efficient way. Nondeterministic ComputationsĪn algorithm is a set of steps of operations to solve a problem performing calculation, data processing, and automated reasoning tasks.
