❔ VB in college

I am taking an intro to computer science as required to fulfill the degree. Anyways, I probably won't be running into VB for the rest of my classes so I am just curious about the value of this short experience. I don't see myself using it again. I am curious about your thoughts.

I wrote this code. The input in this case was "Hacker Rank". It's supposed to output "Hce akr Rn ak". Instead, it outputted "HHHHHHaaaa". I have no idea why this happened. I must've messed up somewhere.

why does it print "you are young" no matter what the input is?

I made this algorithm that is supposed to receive an input and gather all the negative numbers into one variable and positive variables into another. in then divided it by the number of items in the given list.
