Leetcode 2023 😸🐱🐈

Happy New Year! 🎆

Hello 2023! ✨

This year, I'm about to participate in the Daily LeetCoding Challenge 🧗🏻‍♀️ to maintain the good habit of solving Data Structures and Algorithms problems regularly (as some sort of brain workout 🏋🏻‍♀️) Hopefully, I can keep up with this challenge. Though it's not going to be easy, I'll work my fingers to the bone in order to go as far as I can. 🎯

I will be updating this repo every day (hopefully, lol). 📝

Time to say Goodbye! ✋🏻

Today is the last day of April as I conclude my Daily LeetCoding Challenge. In the past four months, I’ve witnessed many ups and downs in the market, and my long-term goal has changed. I have other things to prioritize and focus on now, so I guess it’s time I take a break from LeetCode, as I can’t make enough time for it. 😕

Not sure when, but I’ll come back later. 🎯

Solution posts 📝

During this challenge, I've made some posts on Leetcode with detailed explanations for my solutions. Feel free to leave a comment if you see any room for improvement, I'll greatly appreciate it.
