Why do we need to think computationally?

• To help us program
• To help us solve complex problems more easily
• To help us to think like a computer

What is an Algorithm?

• Something a computer does to think

• A series of steps and instructions with given inputs to produce an output

• Some instructions

• A series of steps and instructions with given outputs to produce an input

What is computational thinking?

• Giving Instructions to a computer

• Thinking like a computer (in binary)

• Using a series of techniques or approaches to solve a problem

• Identifying a problem

Define PATTERN RECOGNITION.

• A sequence of instructions.

• Looking for similarities and trends.

• Breaking a task into smaller tasks.

• Focusing on what is important and ignoring what is unnecessary.

Which of the following is not done by abstraction?
