Interview question of the issue #181 of rendezvous with cassidoo.
You are given a snapshot of a queue of stocks that have changing prices coming in from a stream. Remove the outdated stocks from the queue.
Example:
$ snapshot = [
{ sym: ‘GME’, cost: 280 },
{ sym: ‘PYPL’, cost: 234 },
{ sym: ‘AMZN’, cost: 3206 },
{ sym: ‘AMZN’, cost: 3213 },
{ sym: ‘GME’, cost: 325 }
]
$ stockQueue(snapshot)
$ [{ sym: ‘PYPL’, cost: 234 },
{ sym: ‘AMZN’, cost: 3213 },
{ sym: ‘GME’, cost: 325 }]
Just pnpm i to install all dependencies and then pnpm t to run the tests!
