write an iterative function that takes two parameters and uses repeated subtraction to return the value of a%b
What have you tried, what are you stuck on, what do you not understand?
You mean recursive function…?
I dont understand how to do it
yes i guess a recursive
to subtract what inside the recursive function? Its little confusing
Right but I don’t know what you know. I don’t know if you know any basic python, I don’t know if you know any basic maths, if you understand what they’re asking you
- do you understand what modulo is, eg what the answer to
4 mod 2or to
6 mod 4is? (Python uses the % symbol for modulo - eg
4 % 2)
- do you understand how it is related to repeated subtraction?
- do you understand how to declare, assign and update a variable?
- do you understand how to write a loop?
I know all of that , i just don’t understand how to relate it to subtraction
I know basic python !
10 mod 3
I can get that valie by subtracting 3 from 10, then 3 from the remainder of that and so on over and over until a specific condition is met.
It is a recursive function.
