Binary Search Tree to Greater Sum Tree – Java

Hello there. It is another Sunday morning during the COVID-19 pandemic. The current temperature in the Twin Cities of Minneapolis and St. Paul is about 30F and is sunny. As soon as I finish with this post my wife and I will stop by Target to get some sundries.

Yesterday my wife and I met my older son at Costco in Minneapolis. We get together every other weekend at Costco to do groceries. My wife and I got a 35 lbs. of beef chuck cut. Once we got home we cut smaller manageable portions, put them in bags and placed them in the freezer. We left one portion out. We cut it into smaller pieces, cut some potatoes, onions, garlic and carrots. Put them in a tray in a 550 degree oven for 10 minutes. The beef browned quite nicely. We then put the items in a pressure cook with some water and left them cooking for 1 ½ hours. We served them in on a thin base of very hot brown rice. I had two large servings. It was delicious.

A couple weeks ago one of my wife’s nice told her that there is a Costco store in Minneapolis that seems to sell different items and in larger packages than others. The Costco Minneapolis Business Center Warehouse is located at 3311 Broadway St NE, Minneapolis, MN 55413-4553. We have not visited the store yet.

A couple days ago there was an article by CBS News titled Groceries could see meat shortages by end of week amid plant closings. I read it and twitted it. In addition I sent a message with the link to my two sons. Apparently they both decided to resupply on meats yesterday. One of my sons lives in Madison, WI so he just went to the Costco store near him. The other lives in MN. The one in WI periodically orders a side of beef and a side of pork. I believe he should be fine for a while.

My son who lives in MN decided to visit the Costco store on Broadway Street. He was impressed by the size of the packages of meat. The prices were very appealing. The only drawback for some might be that you need to buy a large and uncut piece (e.g., full rib eye) and when you get home you need to cut in servings, put them in plastic bags, and then store them in a freezer. If you do not do so and just put it in a freezer, you will have to consume it all in a few days after thawing it. You should never refreeze meats. My sons and we at home are used to this process. We get most of our protein at restaurant suppliers. Continue reading “Working with Files – Python”
