📘 Welcome to Part 224 of Code & Debug’s DSA in Python Course! In this video, rearrange a string’s characters in descending order of frequency. The standard pattern is: count with a hash map, then order by frequency using either sorting or a max-heap. We’ll implement both, discuss tie-handling, and analyze time-space tradeoffs. 🔗 LeetCode – Sort Characters By Frequency: https://leetcode.com/problems/sort-characters-by-frequency/description/ 🔗 Companion Reading (Step-by-step with code): https://codeanddebug.in/blog/sort-characters-by-frequency/ 📄 FULL Playlist Sheet (All Videos in Order): https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 🎓 Enroll Free: Master Python DSA Course https://codeanddebug.in/course/master-dsa-with-leetcode 🚀 Advance Python DSA for FAANG (Zero to Hero Course) https://codeanddebug.in/course/zero-to-hero-python-dsa Stay focused and keep coding with Code & Debug.
