The longest string

Problem

Using the reduce method with a block, find and print the longest string in the list 'cat', 'elephant', 'dog', 'fox' — the one with the most characters. A metaoperator will not help here: the block has to compare the two candidates itself.

Example

The program prints:

elephant
