## Data Structures and Algorithms

  
 This repo contains Python code implementing fundamental data structurs and algorithms, along with solutions to specific programming challenges.

   


 ## Stacks

  Q1 : 
Balanced Expressions

  
mplement a function is_balanced(expression) that takes a string containing parentheses, curly braces, and square brackets and determines whether the expression is balanced


  ## Sequences(Lists/Tuples)

   Q.2


     
Remove Duplicates

   
Write a function remove_duplicates(sequence) that takes a sequence (list or tuple) and returns a new sequence with duplicates removed while maintaining the original order of elements.


# Dictionaries

Q.3 
Word Frequency


Implement a function word_frequency(sentence) that takes a sentence and returns a dictionary containing the frequency of each word in the sentence. Ignore punctuation and consider words in a case-insensitive manner.
