CPython Unveils Chained Assignment Mechanics in Python Bytecode Execution 📌 Chained assignments in Python don’t create separate objects-they share the same underlying instance, a bytecode-level quirk that can silently break your code. A deep dive into CPython’s execution reveals how a = b = [] uses COPY and STORE_FAST to assign the same list to multiple variables, exposing a common pitfall for developers working with mutable data. 🔗 Read more: https://lnkd.in/dUfiAJ44 #Cpython #Pythonbytecode #Chainedassignment #Interpreterexecution #Variablebinding

LeetCode #102 – Binary Tree Level Order Traversal | Python Implementation I implemented an iterative BFS approach using a queue to collect nodes level by level. Core Insight: The len(q) snapshot before the inner loop prevents mixing levels. New children added during iteration don't affect the current level's processing count, ensuring clean level separation. Time: O(n) | Space: O(w) where w = maximum tree width #LeetCode #DataStructures #Python #BinaryTree #BFS #LevelOrderTraversal #CodingInterview #SoftwareEngineering

I recently implemented the K-Medoids clustering algorithm from scratch in Python and visualized the clusters using graphs to understand how the algorithm groups data points. #MachineLearning #PythonProjects https://lnkd.in/gczybNGr

Day 12/100 – #100DaysOfCode 🚀 Solved LeetCode #217 – Contains Duplicate (Python). Today I worked on an array problem to determine whether any value appears at least twice in the array. Approach: 1) Sort the array first. 2) Traverse through the array from index 0 to n-2. 3) Compare each element with the next element. 4) If two adjacent elements are equal, a duplicate exists. 5) If no duplicates are found after traversal, return False. Time Complexity: O(n log n) due to sorting Space Complexity: O(1) Understanding how sorting can simplify duplicate detection in arrays 💪 #LeetCode #Python #DSA #Arrays #ProblemSolving #100DaysOfCode

Day 10/100 – #100DaysOfCode 🚀 Solved LeetCode #66 – Plus One (Python). Today I worked on an array manipulation problem that simulates adding one to a large integer represented as a list of digits. Approach: 1) Traverse the array from the last digit to the first. 2) If the current digit + 1 is not equal to 10, simply increment it and return the array. 3) If the digit becomes 10, set it to 0 and carry over to the next digit. 4) If the carry reaches the first digit, add 1 at the beginning of the array. Time Complexity: O(n) Space Complexity: O(1) Understanding how carry propagation works in arrays 💪 #LeetCode #Python #DSA #Arrays #ProblemSolving #100DaysOfCode

Solved the Minimum Window Substring problem using the Sliding Window technique. Goal: Find the smallest substring in s that contains all characters of p (including duplicates). Key Idea • Maintain character frequency • Expand window to include required characters • Shrink window to get the minimum valid substring Time Complexity: O(n) #geekstreak60 #npci #algorithms #datastructures #python #slidingwindow #codingpractice #problemSolving #100DaysOfCode

Day 7/100 – #100DaysOfCode 🚀 Solved LeetCode #27 – Remove Element (Python). Today I practiced the Two Pointer technique to remove all occurrences of a given value in-place and return the new length of the array. Approach: 1) Initialize a pointer k to track the position of valid elements. 2) Traverse the array using index i. 3) If nums[i] is not equal to the given value, assign it to nums[k]. 4) Increment k to expand the valid portion of the array. 5) Return k as the new length.
