Question

I am using GHCi as my interpreter,

The specifications for my assignment are to have a list of tuples of Ints ie

[(Int,Int)]

when I type

let edges = [(0,2),(0,3),(1,2),(2,3)]

GHCi automatically makes the number types Integer instead of Int, so I can’t test my program ie,

:t edges
edges :: [(Integer,Integer)]

How can I force a definition like that to use Int, instead of Integer??

Thanks!

You can specify the type when you enter it like this:

let edges = [(0,2),(0,3),(1,2),(2,3)] :: [(Int, Int)]
