# Problem Solving as a Technique

Most interested for us as for software developers is part where developing algorithms steps and stages are formalised. So, from this prospective,

## steps involved in algorithm development are:

Step1. Identification of input: For an algorithm, there are quantities to

be supplied called input and these are fed externally. The input is to be indentified

first for any specified problem.

Step2: Identification of output: From an algorithm, at least one quantity

is produced, called for any specified problem.

Step3 : Identification the processing operations : All the calculations

to be performed in order to lead to output from the input are to be identified in

an orderly manner.

Step4 : Processing Definiteness : The instructions composing the

algorithm must be clear and there should not be any ambiguity in them.

Step5 : Processing Finiteness : If we go through the algorithm, then for

all cases, the algorithm should terminate after a finite number of steps.

Step6 : Possessing Effectiveness : The instructions in the algorithm

must be sufficiently basic and in practice they can be carries out easily.

## An algorithm must possess the following properties

1. Finiteness: An algorithm must terminate in a finite number of steps

2. Definiteness: Each step of the algorithm must be precisely and

unambiguously stated

3. Effectiveness: Each step must be effective, in the sense that it should

be primitive easily convert able into program statement) can be performed exactly

in a finite amount of time.

4. Generality: The algorithm must be complete in itself so that it can be

used to solve problems of a specific type for any input data.

5. Input/output: Each algorithm must take zero, one or more quantities as

input data produce one or more output values. An algorithm can be written in

English like sentences or in any standard representation sometimes, algorithm

written in English like languages are called Pseudo Code.

That formalising is helpful for understanding how you should approach with development custom algorithms. Peace and read the original article !
