Text Alignment Simulator

This project simulates text alignment operations for a given string and width. It supports four types of alignments:

• Left
• Right
• Center
• Justify

Features

• Overflowing characters precede with '-' and are pushed to a new line.
• Numbers are handled properly, with overflowing numbers pushed to a new line entirely.
• Supports multiple lines of input text.

Requirements

• Python 3.x

Usage

1. Clone the repository:

   git clone https://github.com/your-username/text-alignment-simulator.git
   cd text-alignment-simulator

2. Run the script:

   python align_text.py

3. Follow the prompts to enter the text, width, and alignment type.

Example

Input:

Enter the text (end with an empty line):
This is an example of text alignment simulation.
Overflowing words and numbers are handled appropriately.
123456789012345 should be on a new line if it overflows.

Output:

Enter the width: 20
Enter the alignment (left, right, center, justify): justify

Justify Aligned:
This is an example-
of text alignment-
simulation.
Overflowing words-
and numbers are-
handled-
appropriately.
123456789012345-
should be on a new-
line if it overflows.

Functions

left_align(words, width)

Aligns the text to the left.

right_align(words, width)

Aligns the text to the right.

center_align(words, width)

Centers the text.

justify_align(words, width)

Justifies the text.

align_text(text, width, alignment)

Aligns the text based on the specified alignment.

Time Complexity Analysis

• The time complexity for all alignment functions is O(n), where n is the total number of characters in the input text.
• Each word is processed once, and operations like string joining and slicing are linear in nature.
• Overall, the algorithm efficiently handles the text alignment within linear time.

Trace Example

Input Line:

This is an example of text alignment simulation.

Process:

1. Left Align (width=20):

   • Current line: "This is an" (length 10)
   • Current line: "example of" (length 10)
   • Current line: "text alignment-" (length 14, overflows and breaks at width)
   • Current line: "simulation." (length 11)

   Output:

   This is an example of-
   text alignment-
   simulation.
   

2. Right Align (width=20):

   • Uses the left-aligned output and right-aligns each line:

   Output:

   This is an example-
              of text-
   alignment-
            simulation.
   

3. Center Align (width=20):

   • Uses the left-aligned output and centers each line:

   Output:

   This is an example-
       of text-
       alignment-
      simulation.
   

4. Justify Align (width=20):

   • Similar to left align but spreads words to fill the width where possible:

   Output:

   This is an example-
   of text alignment-
   simulation.
   

---

This example demonstrates how the program processes a single line of input for each alignment type. For more complex cases with multiple lines and varying content, the program's logic ensures proper alignment and handling of overflowing text.
