Bivariance... how often do you use bivariance in your typescript?

I saw it many times, but didn't think about how many problems it could potentially bring.

Also, you can check it in our lovely React ;)

57. Insert Interval

When you merge intervals, you can do it with one iteration, when you want to insert one -- take the first items that are not overlapped, add the overlap item, and add the rest.

91. Decode Ways

A recursive solution is good, but remember to use memoization.
However, an iterative solution with accumulation is much more effective.

73. Set Matrix Zeroes

When you need to make changes "in a place" try to set flags somewhere -> make changes according to the flags -> make changes with elements that contain flags.

@ChShersh can you explain?

124. Binary Tree Maximum Path Sum

It is an interesting task.
You need to choose and move forward with the most appropriate option.

91. Decode Ways

Such a great iterative solution.
You can save a lot if you understand exactly what data you need.

202. Happy Number

This problem looks simple, but it teaches 2 powerful patterns:
1. Detect cycles (think fast & slow pointers)
2. Transform numbers -> sum of squares

It's really cool how this simple task can teach you how to use such a great mechanism.

@ChShersh how?

[Art Em @artbitbyte]

@ChShersh 1st one is at the top.
Why did you decide to learn it?

55. Jump Game

Once you need to make the best possible choice, and it will not make things worse later -- use greedy

2402. Meeting Rooms III

It was hard.

- If you need to choose something, the smallest/biggest, it makes sense to consider the priority queue

The biggest thing this month is here!

A brand new C++ video is out on "Code for Yourself"!
You can tell a lot of hard work went into it. As always, the video is excellent!
