Exercises Part 1

1. Implement function anyLarger, which should return True, if and only if a list of values contains at least one element larger than a given reference value. Use interface Comp in your implementation.

2. Implement function allLarger, which should return True, if and only if a list of values contains only elements larger than a given reference value. Note, that this is trivially true for the empty list. Use interface Comp in your implementation.

3. Implement function maxElem, which tries to extract the largest element from a list of values with a Comp implementation. Likewise for minElem, which tries to extract the smallest element. Note, that the possibility of the list being empty must be considered when deciding on the output type.

4. Define an interface Concat for values like lists or strings, which can be concatenated. Provide implementations for lists and strings.

5. Implement function concatList for concatenating the values in a list holding values with a Concat implementation. Make sure to reflect the possibility of the list being empty in your output type.
