My learnings after solving 700+ LeetCode problems, summarized in a few points.

2 years of experience curated in a thread.🧵 Image 📌Consistency is more important than Intensity:

It happens very often with us that we lack in solving problems daily and get motivated once a week then solve 5 - 10 in one sitting and again forget for a few days.

Are you also tired of Time Limit Exceeded errors on your code??

Open this thread, I promise you'll not face it anymore. 🧵 Image We're solely talking about DSA problems not other things around.

This is one of the most important threads till now, it'll tell you how to find an estimate of the worst-case time complexity of an algorithm that can work in a problem. So read till the end, carefully. 🤯

📢 Never make these mistakes on @LeetCode if you want to excel in problem solving from beginning to end.

A thread. 🧵 Image 📌 If you're just starting out with DSA, don't directly go to LeetCode, your first destination should be HackerRank, you can learn any programming language there and practice the basic concepts in a structured manner.

It's better to solve one problem everyday instead of solving 10 once in a week.
~Consistency

In the series of solving daily @LeetCode challenges, let's see today's really interesting problem.

#100daysOfCode @LeetCode Problem statement:

You are given two string arrays words1 and words2.

A string b is a subset of string a if every letter in b occurs in a including multiplicity.

For example, "wrr" is a subset of "warrior" but is not a subset of "world".

“A son asked his father, why the sun rises in the east, and sets in the west. His response? If it works, don’t touch!”. You know why? 🤔
Coz, his father was a programmer. 😅

Well, jokes apart, in the series of solving @LeetCode, let's see today's problem. Banner @LeetCode We've an easy problem, "Valid Anagram": Given two strings s and t, return true if t is an anagram of s, and false otherwise.

An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once.
