 what is algorithm ?

To make a computer do anything, one need to write a computer program. To write a computer program, one have to tell the computer, step by step, exactly what he want it to do. The computer then “executes” the program, following each step mechanically, to accomplish the end goal.

Dear Friend > Algorithm An algorithm is a set of instructions to be followed to solve a problem. – There can be more than one solution (more than one algorithm) to solve a given problem. – An algorithm can be implemented using different programming languages on different platforms. An algorithm must be correct. It should correctly solve the problem. – e.g. For sorting, this means even if (1) the input is already sorted, or (2) it contains repeated elements. • Once we have a correct algorithm for a problem, we have to determine the efficiency of that algorithm. An algorithm is a specification of a behavioral process. It consists of a finite set of instructions that govern behavior step-by-step http://image.slidesharecdn.com/03algorithmproperties-130108141617-phpapp01/95/03-algorithm-properties-9-638.jpg?cb=1357654618

The computer then “executes” the program, following each step mechanically, to accomplish the end goal. When one tells the computer what to do, he also gets to choose how it’s going to do it. That’s where computer algorithms come in. The algorithm is the basic technique used to get the job done. In informal words Algorithm is a sequence of steps or set of rules in English language to be followed in calculations or other problem-solving operations, esp. by a computer.

**ALGORITHM** To make a computer do anything, one need to write a computer program. To write a computer program, one have to tell the computer, step by step, exactly what he want it to do. The computer then “executes” the program, following each step mechanically, to accomplish the end goal. When one tells the computer what to do, he also gets to choose how it’s going to do it. That’s where computer algorithms come in. The algorithm is the basic technique used to get the job done. In informal words Algorithm is a sequence of steps or set of rules in English language to be followed in calculations or other problem-solving operations, esp. by a computer. Most computer programmers spend a large percentage of their time creating algorithms. (The rest of their time is spent debugging the algorithms that don’t work properly.) The goal is to create efficient algorithms that do not waste more computer resources (such as RAM and CPU time) than necessary. This can be difficult, because an algorithm that performs well on one set of data may perform poorly on other data. Poorly written algorithms can cause programs to run slowly and even crash Thanks

An algorithm is a finite set of unambiguous instructions for carrying out a procedure or for solving a problem, especially on a computer. In mathematics and computer science, an algorithm usually means a recursive procedure that solves a recurrent problem.Simply put, algorithms help people make decisions. E.g.; to find the greatest common divisor of two integers. Algorithms can be expressed in various notations, like natural languages, pseudo-code, flowcharts, programming languages or control tables.The mechanism of applying an algorithm to an input to attain an output is termed as computation.
