How do I return a number between 0 and 4, depending the input number?
For example if I pass it number 23 it will return 3. The number set should look like
0 5 10 15 20 ..
1 6 11 16 21 ..
2 7 12 17 22 ..
3 8 13 18 23 ..
4 9 14 19 24
What’s the math for this?
Use the modulo operation, typically
%in many languages (andmodin many others).
