In the exercise "Equivalent Binary Trees" binary search trees (BST) are used but text uses term "binary tree". I suggest using binary search tree term instead of binary tree as it implies that nodes a…

Given two binary trees and imagine that when you put one of them to cover the other, some nodes of the two trees are overlapped while the others are not.
You need to merge them into a new binary tr…

Given n, how many structurally unique BST's (binary search trees) that store values 1...n?
For example,
Given n = 3, there are a total of 5 unique BST's.

In LSU we are planing to use shift register to keep age order of instructions. Shift registers are linear. Maybe we should consider using the binary trees to keep elements in order? I am not sure if t…

### Description
In https://github.com/elastic/elasticsearch/pull/95809 we prototyped a sorted keys iterator for `LongKeyedBucketOrds`, using a Java `TreeSet`. Using a tree set here has many benefits…

First note that dp[k] represents the number of BST trees built from 1....k;
Then assume we have the number of the first 4 trees: dp[1] = 1 ,dp[2] =2 ,dp[3] = 5, dp[4] =14 , how do we get dp[5] base…
