Unit 1 to 2 two mark question answer 😊

1.Here's a concise 2-mark answer:

An algorithm is a step-by-step procedure to solve a problem or perform a task. It takes input, processes it, and produces output.

2.Here's a concise 2-mark answer:

Recursion vs Iteration:

Recursion:

- Function calls itself repeatedly
- Uses system stack for storage
- Terminates when base case is reached

Iteration:

- Looping construct (e.g., for, while) repeats
- Uses loop variables for storage
- Terminates when loop condition is false

3.Pseudocode is a way of writing code that is similar to programming languages, but it's not actual code. It's a high-level representation of a program or algorithm, using a combination of natural language and programming concepts.

Here's an example of pseudocode for a simple algorithm that calculates the average of three numbers:

Input: num1, num2, num3

Calculate sum = num1 + num2 + num3

Calculate average = sum / 3

Output: average

This pseudocode uses a combination of natural language (e.g., "Calculate sum") and programming concepts (e.g., variables, arithmetic operations) to describe the algorithm. It's not actual code, but it's close enough to be easily translated into a programming language.

4.A flowchart is a graphical representation of a process or algorithm, showing the steps and decisions involved. It's a diagram that uses symbols, arrows, and text to illustrate the flow of a program or process.

Here's an example of a simple flowchart that determines whether a person is eligible to vote:

Start
|
| Is the person 18 years or older?
|
| Yes Proceed to next question
| No Not eligible to vote

Is the person a citizen?
|
| Yes Eligible to vote
| No Not eligible to vote

End

Symbols used in this flowchart:

Rectangle: Process or action
Diamond: Decision or question
Arrow: Flow of control

Flowcharts are useful for:

Visualizing complex processes
Identifying logical errors
Communicating ideas and algorithms

This is just a simple example, but flowcharts can be used to represent much more complex processes and algorithms.

Unit 2

1.Here's a concise differentiation between interactive and script modes:

Interactive Mode
- User interacts directly with the program
- Program responds immediately to user input
- User can modify input or correct errors
- Examples: Command-line interfaces, REPL (Read-Eval-Print Loop)

Script Mode
- Program runs a predefined script or set of instructions
- Program executes the script without user intervention
- User cannot modify input or correct errors during execution
- Examples: Batch files, shell scripts, automated tasks

2.Precedence of operators refers to the order in which operators are evaluated when there are multiple operators in an expression.

Here's a general precedence order for common operators:

1. Parentheses `()`
2. Exponentiation `^`
3. Multiplication `*` and Division `/`
4. Addition `+` and Subtraction `-`
5. Relational operators `==`, `!=`, `<`, `>`, `<=`, `>=`
6. Logical operators `&&`, `||`, `!`
7. Assignment operators `=`, `+=`, `-=`, `*=`, `/=`, etc.

When multiple operators have the same precedence, the expression is evaluated from left to right.

3.Here are the data types in Python (2-mark answer):

1. Numeric: int, float, complex
2. Text: str
3. Sequence: list, tuple
4. Mapping: dict
5. Set: set, frozenset
6. Boolean: bool

4.Here are the rules for variable names in Python (2-mark answer):

1. Start with a letter (a-z, A-Z) or underscore (_)
2. Contain only letters (a-z, A-Z), digits (0-9), and underscore (_)
3. Be unique
4. Not be a reserved keyword
5. Not contain special characters (!, @, #, $, etc.)
