if the 999999999999999999999 is in position 0 of the vector then the index is 0
if it is in position 0 then the value is less than what is in position 1
Maybe you need a function that returns that vector for further manipulation outside matrix
In Task 4 for UN Challenge, I did not understand what I should do in Instead of city_routing use <your-git-nick>-routing. Should I create a new database with a different name and implement pGRouting queries again?
<your-git-nick> == your GitHub username
if GitHub username is xyz the database name should be xyz_routing
Yes, I got that. Should I use Bucaresti_RO.osm again or take any other data to implement pGRouting queries?
You have to load the the same data that is Bucaresti_RO.osm in your new database
