Challenge #13: 🏭 The assembly line

Simulate the path of a gift inside a factory and return how it ends. To do this, you must create a function runFactory(factory).

factory is a string[] where each cell can be:

• > < ^ v movements
• . correct exit

Keep in mind that all rows have the same length and that there will be no other symbols.

The gift always starts at position (0,0) (top left). At each step it reads the current cell and moves according to the direction. If it reaches a cell with a dot (.) it means it has correctly exited the factory.

Result

Return one of these values:

• 'completed' if it reaches a .
• 'loop' if it visits a position twice
• 'broken' if it goes outside the board

Examples

runFactory([
  '>>.'
]) // 'completed'

runFactory([
  '>>>'
]) // 'broken'

runFactory([
  '>><'
]) // 'loop'

runFactory([
  '>>v',
  '..<'
]) // 'completed'

runFactory([
  '>>v',
  '<<<'
]) // 'broken'

runFactory([
  '>v.',
  '^..'
]) // 'completed'

runFactory([
  'v.',
  '^.'
]) // 'loop'
