I'm very new to haskell hugs and would appreciate it if someone could help me out here. I've been giving 2 questions.
1.) A and B are two sets of integers. Implement a function to obtain the integers that belong to both sets. Test your function fully. 2.) Define and test a function f, which, if A is a set of {x, y, z} then f(A) = {{},{x}, {y}, {z}, {x, y}, {x,z}, {y,z}, {x, y, z}} Manage to get the first one. interset::[Int]->[Int]->[Int] interset x [] = [] interset [] y = [] interset x@(xs:xt) y@(ys:yt) = if xs == ys then as:(interset at yt) else interset at y Totally have no clue for the 2nd question. could someone help me out ?
