if len(arr) <= 1:
return arr
pivot = arr[len(arr) // 2]
left = [x for x in arr if x < pivot]
middle = [x for x in arr if x == pivot]
right = [x for x in arr if x > pivot]
return quick_sort(left) + middle + quick_sort(right)
# Test the function
unsorted_list = [3, 6, 8, 10, 1, 2, 1]
print(quick_sort(unsorted_list)) # Output: [1, 1, 2, 3, 6, 8, 10]
2. Solve a Dynamic Programming Problem
Dynamic programming is a powerful technique for solving complex problems by breaking them down into simpler subproblems. Try solving a classic dynamic programming problem like the Fibonacci sequence or the Longest Common Subsequence.
def fibonacci(n, memo={}):
if n in memo:
return memo[n]
if n <= 1:
return n
memo[n] = fibonacci(n-1, memo) + fibonacci(n-2, memo)
return memo[n]
# Test the function
print(fibonacci(10)) # Output: 55
3. Implement a Data Structure
Choose a data structure you’re less familiar with, such as a binary search tree or a hash table, and implement it from scratch. This exercise will deepen your understanding of how these fundamental structures work and when to use them.
class Node:
def __init__(self, key):
self.left = None
self.right = None
self.val = key
class BinarySearchTree:
def __init__(self):
self.root = None
def insert(self, key):
self.root = self._insert_recursive(self.root, key)
def _insert_recursive(self, root, key):
if root is None:
return Node(key)
if key < root.val:
root.left = self._insert_recursive(root.left, key)
else:
root.right = self._insert_recursive(root.right, key)
return root
def inorder_traversal(self):
self._inorder_recursive(self.root)
def _inorder_recursive(self, root):
if root:
self._inorder_recursive(root.left)
print(root.val, end=" ")
self._inorder_recursive(root.right)
# Test the BST
bst = BinarySearchTree()
bst.insert(50)
bst.insert(30)
bst.insert(20)
bst.insert(40)
bst.insert(70)
bst.insert(60)
