WORD SEARCH

INTRODUCTION

A word search program is a computer application or script designed to generate and solve word search puzzles. Word search puzzles are popular games that involve finding and circling words hidden within a grid of letters.

OVERVIEW OF WORD SEARCH

A word search is a popular word puzzle game that involves finding and circling specific words hidden within a grid of letters. The grid is typically square or rectangular, and the words can be placed horizontally, vertically, diagonally, forward, or backward. The objective is to locate all the words in the grid based on a list of given words.

Here's an overview of the key aspects of word searches:

Components of a Word Search:
- Grid: A matrix of letters where the words are hidden.
- Words: A list of words that the player needs to find in the grid.
- Direction: Words can be placed in various directions—horizontally, vertically, diagonally, forward, or backward.
Creating a Word Search:
- The process of creating a word search involves selecting words, determining their positions in the grid, and filling the remaining spaces with random letters.
- Designers often ensure that words do not overlap and are distributed in a balanced manner across the grid.
Solving a Word Search:
- Players search for the words in the grid based on the given list.
- Words are usually circled or marked to indicate that they have been found.
- Some word searches have additional challenges, such as hidden themes or extra letters that form a message when read in order.
Educational Applications:
- Word searches are widely used in education to reinforce vocabulary and spelling skills.
- They are suitable for various subjects, allowing educators to create puzzles related to specific topics or lessons.
Entertainment and Relaxation:
- Word searches are commonly found in newspapers, magazines, puzzle books, and online platforms as a form of entertainment.
- Many people enjoy solving word searches for relaxation and as a leisure activity.
Digital Word Searches:
- With the advent of technology, digital versions of word searches are prevalent in mobile apps, websites, and software.
- Digital word searches often offer features like dynamic puzzle generation, different difficulty levels, and interactive solving experiences.
Customization and Themes:
- Word searches can be customized for specific occasions or themes. For example, holiday-themed word searches or puzzles related to a particular field (e.g., science, sports) are common.
- Themes can add an extra layer of interest and challenge to the puzzle.
Variations:
- Some word searches have variations, such as crosswords combined with word search elements or word searches with hidden messages formed by unused letters.

Overall, word searches are versatile puzzles enjoyed by people of all ages. They serve as a valuable educational tool, a source of entertainment, and a relaxing pastime

Problem Statement:

You are tasked with creating a Python program that generates a word search puzzle. The program should take a list of words and create a grid where these words are hidden in various directions. Users should be able to interact with the program to find the hidden words.

STEP-BY-STEP EXPLAINATION

The random library is used for generating random values, crucial for placing words randomly in the grid.
The generate_word_search function initializes an empty grid with spaces. The size of the grid is determined by the size parameter. It's a square grid.
For each word in the list, the program randomly chooses a direction ('horizontal', 'vertical', or 'diagonal') and selects a random starting position (row,col) within the grid.
Depending on the chosen direction, the program checks if the word can fit in that direction without going out of bounds. If it can, the program places the letters of the word in the corresponding positions in the grid.
After placing the words, the program fills the remaining empty spaces in the grid with random letters. The function returns the final word search grid.
The display_word_search function takes a grid as input and prints it row by row, separating each letter with a space .The word_search function initializes a list of words and a grid size. It generates a word search puzzle using the generate_word_search function, displays the puzzle using display_word_search , and prints the list of words to find.
This block ensures that the word_search function is executed when the script is run as the main program.

Test Case 1: Null List of Words

Input:

Enter the words to include in the puzzle (separated by spaces): Enter the size of the puzzle grid: 5

Explanation: In this case, an empty list of words is provided. The output should be an empty grid with random letters.

Test Case 2: True Word Search

Input:

Enter the words to include in the puzzle (separated by spaces): PYTHON CODE SEARCH Enter the size of the puzzle grid: 10

Explanation: The input includes words "PYTHON," "CODE," and "SEARCH." The program should generate a word search grid containing these words in random directions.

Test Case 3: False Word Search

Input:

Enter the words to include in the puzzle (separated by spaces): HELLO WORLD Enter the size of the puzzle grid: 3

Explanation: The grid size is too small to accommodate the words "HELLO" and "WORLD" in any direction. The output should be a grid with random letters.

TIME AND SPACE COMPLEXITY

TIME COMPLEXITY:

Word Placement:
- For each word in the list, the program randomly selects a direction and a starting position in the grid. This operation is done for each word independently.
- Time complexity for placing each word is O(L), where L is the length of the word.
Grid Filling:
- Filling the remaining empty spaces in the grid with random letters has a time complexity of O(N), where N is the total number of cells in the grid.
Overall:
- If we have W words and a grid of size N x N, the overall time complexity is approximately O(W * L + N^2).

SPACE COMPLEXITY:

Grid Storage:
- The program uses a 2D vector to represent the grid. The space complexity for storing the grid is O(N^2).
Random Number Generation:
- The program uses random number generation for selecting directions and positions. The space complexity for this is typically O(1).
Overall:
- The overall space complexity is O(N^2).

Here, W is the number of words, L is the average length of words, and N is the size of the grid.
