Introduction to Algorithms
What is an algorithm ?
The word Algorithm means ” A set of rules
to be followed in calculations or other
problem-solving operations ” Or ” A
procedure for solving a mathematical
problem in a finite number of steps
frequently by recursive operations “.
Therefore Algorithm refers to a sequence of
finite steps to solve a particular problem.
Algorithms can be simple and complex
depending on what you want to
achieve.
We need to pick the “BEST” algorithm
There can be multiple ways to solve a
problem, but we want to minimize some
criteria in the procedure :
1. Time required to solve the problem
(Time complexity)
2. Extra space required to solve the
problem (Space complexity)
