Hi,

I want to create an immutable array like this

In .hs file

e = [1,2,3]

a = array [1,3] [(i,v) | i<-[1..3], v<-e]

I expect the output to be

“array (1,3) [(1,1),(2,2),(3,3)]”

But I got

“array (1,3) [(1,3),(2,3),(3,3)]”

Why is that? Can anyone tell me how to get the output that I expect?

Thanks a lot,

cchang
