System Architecture & Design Skills

Big O Complexity Analysis

Complexity	Name	Example
O(1)	Constant	Hash lookup
O(log n)	Logarithmic	Binary search
O(n)	Linear	Array scan
O(n log n)	Linearithmic	Merge sort
O(n²)	Quadratic	Nested loops
O(2ⁿ)	Exponential	Power set

Common Data Structures

    BST:        O(log n) balanced, O(n) worst

Design Patterns

# Singleton with thread safety
from threading import Lock

class Singleton:
    _instance = 
    _lock = Lock()

     ():
         cls._instance  :
             cls._lock:
                 cls._instance  :
                    cls._instance = ().__new__(cls)
         cls._instance


 :
    _services = {}


     ():
        cls._services[name] = service_class


     ():
        service_class = cls._services.get(name)
          service_class:
             ValueError()
         service_class(**kwargs)
