Problem statement

Process commands in a virtual environment:

  • goto <bucket_name> changes the current bucket. The bucket is guaranteed to exist.
  • create <filename> creates that file in the current bucket. If the same filename already exists in that bucket, nothing happens.

Return the bucket containing the largest number of distinct files after all commands. The first command is a goto, at least one command is a create, and the largest bucket is unique.

Function

databricksGotoLargestBucket(commands: String[]) → String

Examples

Example 1

commands = ["goto bucketA", "create fileA", "create fileB", "create fileA", "goto bucketB", "goto bucketC", "create fileA", "create fileB", "create fileC"]return = "bucketC"

bucketA contains two distinct files, bucketB contains none, and bucketC contains three.
