You work for a tourism agency, and your job is to promote amusement parks. You have been given a list of amusement parks and you need to write code to help organize the data.
Your mission, should you choose to accept it, is to group amusement parks by
- ID
- Country
- Country / State
You need to provide a way to get extremely fast access to amusement parks by their ID.
So given the following array:
[
{
:id=>546,
:name=>"Kalahari Resorts",
:city=>"Wisconsin Dells",
:state=>"Wisconsin",
:country=>"United States"
},
{
:id=>547,
:name=>"Little Amerricka",
:city=>"Marshall",
:state=>"Wisconsin",
:country=>"United States"
}
]Your code should produce the following hash:
{
546 => {
:id=>546,
:name=>"Kalahari Resorts",
:city=>"Wisconsin Dells",
:state=>"Wisconsin",
:country=>"United States"
},
547 => {
:id=>547,
:name=>"Little Amerricka",
:city=>"Marshall",
:state=>"Wisconsin",
:country=>"United States"
}
}So given the following array:
[
{
:id=>546,
:name=>"Kalahari Resorts",
:city=>"Wisconsin Dells",
:state=>"Wisconsin",
:country=>"United States"
},
{
:id=>547,
:name=>"Little Amerricka",
:city=>"Marshall",
:state=>"Wisconsin",
:country=>"United States"
},
{
:id=>2,
:name=>"Calaway Park",
:city=>"Calgary",
:state=>"Alberta",
:country=>"Canada"
}
]Your code should produce the following hash:
{
"Canada" => [
{
:id=>2,
:name=>"Calaway Park",
:city=>"Calgary",
:state=>"Alberta",
:country=>"Canada"
}
],
"United States" => [
{
:id=>546,
:name=>"Kalahari Resorts",
:city=>"Wisconsin Dells",
:state=>"Wisconsin",
:country=>"United States"
},
{
:id=>547,
:name=>"Little Amerricka",
:city=>"Marshall",
:state=>"Wisconsin",
:country=>"United States"
}
]
}Given the following array:
[
{
:id=>3,
:name=>"Galaxyland",
:city=>"Edmonton",
:state=>"Alberta",
:country=>"Canada"
},
{
:id=>4,
:name=>"Heratage Park",
:city=>"Calgary",
:state=>"Alberta",
:country=>"Canada"
},
{
:id=>6,
:name=>"Playland (Vancouver)",
:city=>"Vancouver",
:state=>"British Columbia",
:country=>"Canada"
},
{
:id=>8,
:name=>"Crystal Palace Amusement Park",
:city=>"Dieppe",
:state=>"New Brunswick",
:country=>"Canada"
}
]Your code should return the following hash:
{
"Alberta, Canada" => [
{
:id => 3,
:name => "Galaxyland",
:city => "Edmonton",
:state => "Alberta",
:country => "Canada"
},
{
:id => 4,
:name => "Heratage Park",
:city => "Calgary",
:state => "Alberta",
:country => "Canada"
},
],
"British Columbia, Canada" => [
{
:id => 6,
:name => "Playland (Vancouver)",
:city => "Vancouver",
:state => "British Columbia",
:country => "Canada"
},
],
"New Brunswick, Canada" => [
{
:id => 8,
:name => "Crystal Palace Amusement Park",
:city => "Dieppe",
:state => "New Brunswick",
:country => "Canada"
}
]
}Run your code against the data in data/amusement_parks.yml.
