Data Structures and Algorithms: Word Search I and II šŸš€

Welcome to this in-depth guide on Word Search, a fundamental algorithm used in many applications, from text editors to search engines. By the end of this lesson, you'll have a solid understanding of Word Search I and II, their applications, and how to implement them in your own projects. šŸŽÆ

Understanding Word Search šŸ”

Word Search is a technique used to find specific words or patterns within a larger body of text. It's a crucial algorithm in areas such as text editing, web search, and natural language processing.

Word Search I šŸ“

Word Search I is a basic version of the algorithm that checks if a given word exists in a single line of text.

Implementation šŸ’»

python
def word_search_I(text, word): # Iterate through the text for i in range(len(text) - len(word) + 1): # Check if the substring matches the word if text[i:i+len(word)] == word: return True # Word found, exit the loop return False # Word not found

Word Search II šŸ’»

Word Search II is an extension of Word Search I that can find a given word in a multi-line text.

Implementation šŸ’»

python
def word_search_II(text, word): for line in text.split('\n'): # Use Word Search I to check the current line if word_search_I(line, word): return line # Word found, return the line return None # Word not found
