As you know, I have been doing a lot of algorithm questions lately. This week let’s talk about another classic interview question that often comes out: Meeting Room II (Leetcode #253).

In today’s blog, we will talk about another back it again at the algorithm question. This time is a little bit harder. I usually solve Breadth-First-Search (BFS) in a tree problem. Never in my life have I solved it with a non-tree data structure. For that reason, this problem is…

This week I encountered many interval questions in binarysearch.com and leetcode. Since I struggle from time to time on this topic, I would love to write a blog regarding interval topics. Today we are going to discuss leetcode #435 Non-overlapping Intervals.

Here is the question:

Back at it again with another algorithm blog! Today we will talk about one of the popular questions in Leetcode, #647 Palindromic Substrings. There are many ways to solve this problem. We are going to talk about ‘ expand around possible centers here.

Here is the question:

We want to…

Hello, today’s topic is back at it again with the algorithms blog. Today we are going to talk about leetcode question #724 Find Pivot Index. Before we are trying to solve the question, we should understand what prefix sum is.

What is the Prefix Sum?

Prefix sum in the array is iterating through index 1…

This week’s blog is going to be different than usual. Let’s take a break from tech and talk about human beings. Recently I saw many people talking about imposter Syndrome in the job searching process. Imposter syndrome is a common experience for everyone; we all have been through imposter syndrome…

Developers often spend much time deciding the correct data structure to use. Choosing the right data structure can make it easier to operate data, saving time, and making code more comprehensive. The two most prevailing data structures for storing collections of data are Objects and Arrays. Developers use Objects to…

This article will show a quick introduction of a for loop, a forEach, a for of, and a for in. We are going to talk about what are their differences and similarities in this article.

For Loop

This method is the most traditional type of iteration in Javascript. It takes three expressions…
