Definition

• Algorithm can be defined in several ways
• It is a set of rules that gives a particular
  output.
• A formula that is required for solving a problem.
• A small procedure that gives a particular result.
• Sequence of explicit instruction.

Important symbols used in Algorithm

1. Theta (?) It symbolizes the worst case runtime
   of an algorithm.
2. Big O (O) It symbolizes the Average case runtime
   of an algorithm.
3. Omega (? ) It symbolizes the best case runtime
   of an algorithm.

Importance of studying Algorithm

• It have an important role in designing all the
  technological device.
• It sets up the challenge to complete the given
  task.
• Helps in development of pattern recognition
  skill.
• Develop analytical skills to compare two problem
  and get accurate solution.
