Reverse String II

The end of my workday is approaching shortly. Hopefully I will be done with this post soon; otherwise will finish it tomorrow.

Earlier today I was snooping around in the LeetCode website. For the first time I ran into a page that shows every submission you make for a problem. Perhaps I am mistaken, but it seems that the site counts as attempts every submission you make. For example, you ran your first pass and let’s say it is accepted but you want to learn more by improving performance. You may even generate one or more implementations. It seems that they count against you. This seems awkward to me. If I am trying to learn I should not be penalized. If my assumption is incorrect, PLEASE LEAVE ME A NOTE BELLOW SETTING ME STRAIGHT.

Reverse Words in a String

I am a morning person and I do not seem to need eight hours of sleep a day. Earlier this morning (around 01:00 AM) I woke up and browsed the news on my phone. Most (never generalize) were not worth reading. They seem to have a catchy title, but after a few sentences a political message that had nothing to do with the main topic would come up. To top it off you have to reference the information from different sources due to the amount of fake news circulating in most (never say all) platforms.

My wife and I left a window in the kitchen open overnight. We both tend to sleep better with fresh air. Given that we live in the Twin Cities of Minneapolis and St. Paul, sooner rather than later we will have to keep the windows closed and the furnace on.

I just picked a random problem from LeetCode. Problem 151 Reverse Words in a String calls for reversing the order of words in a string. If interested please take a look at the description and spend a few minutes figuring out how to tackle the problem… Continue reading “Reverse Words in a String”

A or B

Over the weekend I watched the YouTube video “Dealing with Negative Comments | AMA #3 – Ask Me Anything with Lex Fridman”. I have watched a few of his videos. I do enjoy them to the point that I have subscribed to them. There is one in which Lex interviews Donald Knuth and other where he interviews Andrew Ng. Both videos are over an hour so I will watch them over the weekend.

If you are interested in getting information about Lex Fridman you can find it here or there.

I picked the challenge “A or B” from HackerRank after receiving an email message. I guess that if you solve a few of their problems they like you to continue visiting their site and solving additional challenges. I like to work on one or two a week. I believe it is the only way to learn and / or refresh material. Continue reading “A or B”
