What is a string?

A type of data that stores a sequence of characters in a specific order. Strings are used to represent text, names, and other textual information.

What is a for loop?

A loop that iterates over a block of code a specified number of times. It is controlled by a counter variable that changes its value with each iteration.

What is an if statement?

A programming statement that causes a flow of control to branch based on the evaluation of a condition. If the condition is true, one set of statements will execute. If the condition is false, another set of statements will execute.

What is an integer?

A variable that holds a numerical value. Integers can be positive, negative, or zero. They do not have decimal points.

What is debugging?

A process in programming used to test and evaluate the execution flow of a program by stepping through the code line by line. It helps identify errors and understand the program's behaviour.

Study Notes

Code Output

The code consists of nested for loops.
The outer loop iterates from i = 2 down to i = 1.
The inner loop iterates from j = i up to j = 2 * i - 1.
The code prints the values of i and j.

Output Analysis

When i = 2, the inner loop iterates from j = 2 to j = 3.
- It prints 22, 23.
When i = 1, the inner loop iterates from j = 1 to j = 1.
- It prints 11.
Combining these outputs, the final output is 22231.
