An algorithm is a step-by-step procedure to solve a problem using a finite number of instructions. To create an algorithm, it must have clear inputs and outputs, unambiguous steps that terminate in a finite number of steps, and each step must be feasible to carry out using paper and pencil. Algorithms use conditional patterns and comments to help with modifications. A flowchart provides a visual representation of an algorithm using blocks like start, stop, assignment, processing, input, output, and conditional statements to depict the sequencing and repetition of instructions.

2. “A Sequential solution of any program
that written in human language,
called Algorithm.”
“It may defined as the step – by – step
procedure to solve a problem with
the help of finite number of
instructions.”

3. Algorithm is the first step of the
solution process, after the
analysis of problem,
programmer write the algorithm
of that problem.

4. Rulesfor constructing
To create an algorithm, keep
following points in mined as :-
Input :- There should be zero or
more values which are to be supplied.
Output :- At least one result is to be
Produced.

5. Definiteness :- Each step must be
clear and unambiguous.
Finiteness :- If we trace the step of an
Algorithm, then for all cases, the
Algorithm must terminate after a finite
number of steps.

6. Effectiveness :-
Each step must be sufficiently basic
that a person using only paper and
pencil can in principle carry it out. In
addition, not only each step is definite,
it must also be a feasible .

7. Comment Session :-
comment is additional info of
program for easily modification.
In algorithm comment would be
appear two square bracket [].

8. CONDITIONAL PATTERNS
STEP 1 :- Start
STEP 2 :-Read two numbers
[n1 and n2]
STEP 3 :- If n1 > n2, go to step 5
STEP 4 :- Print “n2 is biggest” and
go to step 6
STEP 5 :- Print “n1 is biggest”
STEP 6 :- Stop

9.  A flowchart may be defined as
the pictorial representation of
an algorithm. A visual
inspection of flowchart provides
us an idea of sequencing of
instructions and repetition of
groups.
