Haskell simple source code

Hi, I just need a code that generates all ternary trees of depth n in Haskell. A generated tree should be output in one line on console, such as the following example (or anything else that is obvious): R-101 001 001-110 000 111 000 000 011 000 000 001 Remember, I want ALL generrated trees, not just one random tree The above example, if I output it in multiple lines would probably make more sense: R 101 001 001 110 000 111 000 000 011 000 000 001 Each "1" represents a node, while "0" represents no node. Notice that the root is always R, a single node. The above example is a simple ternary tree. from the next depth below the node, we always have N bits of 0 or 1, because it's all the possibilities. I don't need the formula to count it, because the formula is obvious and I have it. I just need the one-line string outputs for the ternary trees of depth n. This is simple, just a long description, but maximum 20-30 lines of code. Do not bid over budget, you will be ignored!
