In this video I put that to the test, solving the Arrays & Hashing section live and unscripted, mistakes included. In this video I talk about: Speedrunning Neetcode 150's Arrays & Hashing section live, no prep Why Python syntax (not DSA knowledge) is what actually trips you up after a break Contains Duplicate, Valid Palindrome, Group Anagrams, Top K Frequent Elements Product of Array Except Self using the prefix/suffix product pattern Two Sum II using binary search with constant space Why practicing out loud is the closest thing to real interview prep My honest take on Neetcode's platform vs. LeetCode ≥ TIMESTAMPS 0:00 Intro — 100 days without LeetCode 0:57 Neetcode copying LeetCode's UI (rant) 2:05 Contains Duplicate 4:09 Valid Palindrome 6:47 Group Anagrams 12:54 Top K Frequent Elements 17:00 Two Sum 17:30 Product of Array Except Self 28:22 Valid Palindrome revisited 29:16 Two Sum II (binary search) 38:19 Wrap-up & next session preview
