Our society is linked to networks such as instagram, telephones, television, roads, bodies of water and even schools. If each of these connections weren't efficient, our world wouldn't be as simple as it is today. Time will be lost and a lot of things will be a lot more time consuming. The way our society is linked allows to save time and energy, making our world easier by making us use less of what we need to and saving us time and effort. Things like electricity, money and water are hings that we save by having these networks.
It took me at least 9 connections to connect the 10 computers.
If there were n number of computers, I have to use n-1 wires.\
The strategy I used to solve this problem was to connect the shortest routes. That way I can use the minimal amount of spanned trees.
