Question

Hello I need to check if two lists have same elements in same order but I wasn't able to achieve as it seems like scheme eq? and eqv? checks by reference so giving false to such:

> (eq? (list 1 2 3) (list 1 2 3))
#f
> (eqv? (list 1 2 3) (list 1 2 3))
#f

How to achieve this ?

Answer 1

This site explains the difference between those operators. But essentially, you want to use equal? when you want to compare the contents of two objects.

Answer 2

seems like equal? and eq? are seperate procedures where equal checks as I needed:

> (equal? (list 1 2 3) (list 1 2 3))
#t
