Invalid Transactions
A transaction is possibly invalid if:
- the amount exceeds
$1000, or - it occurs within and including
60minutes of another transaction with the same name in a different city.
You are given an array of strings transactions where transactions[i] consists of comma-separated values representing the name, time in minutes, amount, and city of the transaction.
Return a list of transactions that are possibly invalid. You may return the answer in any order.
Example 1
Input
transactions = ["alice,20,800,mtv","alice,50,100,beijing"]Output
["alice,20,800,mtv","alice,50,100,beijing"]The first transaction is invalid because the second transaction occurs within a difference of 60 minutes, has the same name, and is in a different city; similarly, the second one is invalid too.
Example 2
Input
transactions = ["alice,20,800,mtv","alice,50,1200,mtv"]Output
["alice,50,1200,mtv"]Only the second transaction is invalid because its amount exceeds $1000.
Constraints
- transactions.length <= 1000
- Each transactions[i] takes the form "{name},{time},{amount},{city}"
- Each {name} and {city} consist of lowercase English letters, and have lengths between 1 and 10.
- Each {time} consist of digits, and represent an integer between 0 and 1000.
- Each {amount} consist of digits, and represent an integer between 0 and 2000.
