Time Window problem

Ruby class which can tell you whether the current time (or any given time) is within a particular "time window."

Time windows are defined by strings in the following format:

• 0700-0900 means every day between these times

• Sat Sun means all day Sat and Sun, no other times

Time ranges should exclude the upper bound, i.e. 0700-0900 is 07:00:00 to 08:59:59. An empty time window means "all times everyday".

Reducer solution for Ruby Code quiz

A local variable named log contains an array of hashes with timestamped events like so

log = [
  {time: 201201, x: 2},
  {time: 201201, y: 7},
  {time: 201201, z: 2},
  {time: 201202, a: 3},
  {time: 201202, b: 4},
  {time: 201202, c: 0}
]

Please collapse the log by date into an array of hashes containing one entry per day

[
  {time: 201201, x: 2, y: 7, z: 2},
  {time: 201202, a: 3, b: 4, c: 0},
]

Ordering in the input is not defined. Ordering in the result is not important. Do not rely on the names of the hash keys other than :time. The field below executes your code in a Sandbox with $SAFE=4, so you can't define new classes, use global variables, etc. The field will turn green if your solution returns a correct object.
