Binary trees have an elegant recursive pointer structure, so they are a good way to learn recursive pointer algorithms. Binary Tree Structure -- a quick introduction to binary trees and the code that operates on them Section 2.
Flip through the story below to see my take. Jeff tracked a few key data elements for what turned out to be a very interesting week: This week I was juicing.
My first postcard on steroids. I was supposed to go to the Tapestry conference in Colorado.
I arrived at the airport for my flight, which was scheduled early in the morning. The plane was delayed hour after hour and ultimately canceled. By the end of the day I had to make a quick decision. Am I going to fly out to Tapestry later, missing the opening night and then turn around and come home the following night on a red eye?
After 7 hours in the airport and not positive on when I would get there, I ended up giving up on the trip and going home. I was looking forward to the conference, so this was really depressing. However, it turned out to be a good decision.
The next morning I woke up at 6am and I couldn't walk, more specifically, I couldn't put any weight on my right leg. I ended up in urgent care that morning followed by 3 other doctor visits over the next 2 days for various tests.
They ruled out all kinds of things, but they never figured out what the problem was. I ended up on steroids and over the course of a few days things started to get better. Eventually I was back to normal about a week later and I've been fine ever since.
It was really strange, but in hindsight, I'm glad I wasn't at the Tapestry conference when this happened. It was also my birthday, which I spent with various doctors and then sitting on my couch in pain with my legs up.
Not the best birthday I've had, but lots to be thankful for, since I recovered quickly and all the tests were fine. For the postcard, I decided to simply list a few key data points.
When I thought of data, I thought of binary. So the postcard simply lists the following data points for the week. There are so many different ways to create this one in Tableau, but I kept it super simple. I placed a text box on a dashboard and put the binary code in a text box.
Then I colored the text to match the postcard and I made sure I picked a clean mono-spaced font so the numbers showed up equally spaced Times New Roman did the trick.
Only three more weeks to post. Next week we look at our phones.
Jeff examined the hours of sleep this week: I was a little worried about this week's data set. I don't have a great sleep pattern and I was wondering what this week was going to look like.
It actually looks more "normal" than I expected. At least there was some consistency. Had I tracked another week it probably would have looked much worse. As for the data collections, there wasn't much to it.
I simply tracked what time I went to bed and when I woke up.
I am rarely asleep before midnight, which is evident in this week's data.Question: Given two binary trees, find if they are structurally identical. Input: 2 trees are given. (Root pointers) Output: TRUE When we say structurally identical trees, we mean that both the trees have exactly the same number of nodes, arranged in the exactly same way.

Python is the last major release in the 2.x series, as the Python maintainers have shifted the focus of their new feature development efforts to the Python 3.x series. The busy beaver game consists of designing a halting, binary-alphabet Turing machine which writes the most 1s on the tape, using only a limited set of states.
The rules for the 2-state game are as follows: the machine must have two states in addition to the halting state, and; the tape starts with 0s only.
