Hello,all
My intention is to generate 50 random coordinates like (x,y).
myrand :: Int
myrand = randomRIO(1::Int, 100)
rf=[(myrand, myrand) | a <- [1..50]]
My short program is like this. However, GHCI say that the return type of
randomRIO is IO a while the function defined by me is Int. Since I
Good. I personally perfer this solution...

Like given a string list s="This is the string I want to test", I want to get
the substring. In ruby or other language, it's simple like s[2..10], but how
to do it in Haskell?

Hi, all
I’m just a newbie for Haskell and functional
programming world. The idea I currently read is quite different and
interesting.
I have one general question about the recursively
looping style. For example:
myMax [ ] = error “empty list”
myMax [x] = x
myMax [x:xs] = if x>= (myMax
