#Neetcode

When you're preparing for technical interviews, you should solidify your knowledge of algorithms & data structures. And many devs use LeetCode to help them practice and study. In this course, you'll work through the Neetcode 150 (the 150 most essential LeetCode problems) to really hone your skills.

Day 12/150 Problem: Longest Substring Without Repeating Characters Used a sliding window with two pointers to track the longest stretch of unique characters. Each char’s last seen index lets me skip duplicates in O(1) time. ⏱️ O(n) time | 💾 O(k) space #NeetCode #100DaysOfCode

11/150 NeetCode 🚀 Solved Container With Most Water Problem. Used the two-pointer technique expanding inward from both ends to find the max area efficiently. 📊 Time: O(n) 📦 Space: O(1) #NeetCode150 #LeetCode #100DaysOfCode

Oct 25 | Sunday 🌷 - 6 hr sleep - Meditated - LeetCode contest: solved 4092. - 101. Symmetric Tree 543. Diameter of Binary Tree - online exam done - DBMS qp (low attendance 😭) - studying DAA rn - 900 steps today. Didn't step out #LeetCode #DSA #100DaysOfCode

Doing multiple approaches for a problem. Genuinely my mind stuck in a loop😮‍💨 But whatever no other way to get good at this. #dsa #leetcode #neetcode #striver #cpp #cp #faang #interview #striver #dailycode
