bumplan

A simple program that finds the seating arrangement for passengers for a given custom airplane seat layout.

📣 Note that this project was purpose-built for a coding challenge (see problem statement).

Before you run this app, make sure you have Node.js installed. yarn is recommended, but can be used interchangeably with npm.

git clone https://github.com/paambaati/bumplan
cd bumplan
yarn install && yarn build

yarn start "<seat_layout>" "<passengers_count>"

yarn run coverage

🧩 Design

The program first builds a "mapping" for the given layout (see buildSeatMapping()). Essentially, the input 2D array is flattened and a lookup table is built, along with the seat types.

For example, for the layout —
```
[[1, 2], [3, 2]]
```
The mapping built is —
```
{
    '0_0_0': 'W',
    '1_0_0': 'A',
    '1_1_0': 'M',
    '1_2_0': 'W',
    '0_0_1': 'W',
    '1_0_1': 'A',
    '1_1_1': 'M',
    '1_2_1': 'W'
}
```
The mapping is then used to filter by seat types first and then iterated over to assign passenger number (see assignSeats()). As a nice bonus, the method will also optionally take a priority list, so it will be easier to alter the seating rules in the future.
The seat assignment is then printed on the screen (see printSeatAssignments()). It uses the super-lightweight colorette to print in colors to quickly distinguish the seat types.
