Answer 1

Give input like this
Name
100
200

Not like this in one line
Name 100 200 --> it's wrong way
Beacuse in Sololearn you give input line by line

Answer 2

There is no error please note the code require 3 input, you should enter them at the start separated by new line try this input

Name
50
90
