Sam and Substrings

It is a sunny Tuesday in the Twin Cities of Minneapolis and St. Paul. The earlier forecast was calling for thunderstorms. I just check the revised forecast and it seems that we might have some rain after dark. That is good news because my wife and I are invited to our oldest son’s house today to have the next version of the burgers we had last Saturday as I commented on the Roads and Libraries post. Will let you know tomorrow how it goes.

As I mentioned in a previous post, a few weeks ago I had elective surgery performed on my left knee. All is going very well with the recovery process. So far most of the physical therapy sessions have been on Tuesdays and Thursdays towards the end of the day (04:30 PM or 05:00 PM). Today the session is at 01:30 PM. My wife changed our daily lunch schedule to accommodate it. We will be having lunch after therapy.

Yesterday we spoke over Skype with a couple friends of us that live in Peru. Things are not going well in Peru or Latin America in general. Seems that communism is creeping at alarming rates. In the next presidential elections to be held on June 06, 2021 there are two candidates. One candidate represents the right and the other the left. The left has mandated voters in different places to take a picture of their secret ballot to allow party representatives to verify that the votes are for the communist candidate. If voters refuse their lives would be in danger. Not much to say about a secret and fair election!

Of course the bottom line is always money. In this case some foreign nations will benefit by getting several mines at a much discounted price. It seems like a repeat of what transpired and is still going on in Venezuela. Such is life. Continue reading “Sam and Substrings”

Validate Binary Search Tree

It is a gloomy day in the Twin Cities of Minneapolis and St. Paul. The good thing is that we have about two days until Thanksgiving Day 2020. This year we are cooking an 11 lbs. turkey. Typically my wife and I make an 18+ lbs. bird. Not only that but we are dropping half of it at our granddaughters place. On Thanksgiving Day we will be connecting with family via Jitsi and Skype.

Finding Intersection

Earlier this morning I spoke with my friend Gustavo. We know each other for most of our lives. We started kindergarten together. Today we are both married to our respective spouses and have kids and grand kids. We get on Skype about once a month always on a Friday at 06:00 AM and have a great time catching up.

He studied geology and currently owns a company that was started by his dad. He bought out his siblings and with time has grown his company quite a lot. Last time we got together was for a geology convention last year in the Twin Cities of Minneapolis and St. Paul. We had a great time with our spouses dining, dining and doing tourist things. The only thing of the trip they did not like was the snow. The show was in February and there was a lot of snow and of course cold temperatures. Continue reading “Finding Intersection”

Absolute Permutation

UPDATE:  The technical issue that prevented me from posting a solution was promptly resolved by HackerRank. I received a message indicating all was well to proceed.

It is Sunday and a sunny day in the Twin Cities of Minneapolis and St. Paul. I tried solving the Absolute Permutation challenge from Hacker Rank but ran into an issue. Will comment on it and show my solution which at this time has not been accepted.

Today is Mothers Day. If you are a mom hope you enjoy the day with your family. My wife and I have two sons. One lives in Indiana, and the other in Minnesota. The one in Minnesota stopped by yesterday afternoon with flowers and his two kids. Earlier this morning our son and wife called to wish my wife a nice day. Continue reading “Absolute Permutation”
