pygorithm.data_structures - Collection of data structure examples
PACKAGE CONTENTS

trie
#Example 1:
# import the required data structure
from pygorithm.data_structures import stack
# create a stack with default stack size 10
myStack = stack.Stack()
# push elements into the stack
myStack.push(2)
myStack.push(5)
myStack.push(9)
myStack.push(10)
# print the contents of stack
print(myStack)
# pop elements from stack
myStack.pop()
print(myStack)
# peek element in stack
print(myStack.peek())
# size of stack
print(myStack.size())
Output:2 5 9 10
2 5 9
9
3
#Example 2:
# to get code for BinarySearchTree
BStree = tree.BinarySearchTree.get_code()
print(BStree)

Example 3:
To get complexities for the following scripts:# create a stack with default stack size 10
Bsort = sorting.bubble_sort.time_complexities()
Output:Best Case: O(n), Average Case: O(n ^ 2), Worst Case: O(n ^ 2).
For Improved Bubble Sort:
Best Case: O(n); Average Case: O(n * (n - 1) / 4); Worst Case: O(n ^ 2)
