A transaction is possibly invalid if:
the amount exceeds $1000
, or;
if it occurs within (and including) 60
minutes of another transaction with the same name in a different city.
You are given an array of strings transaction
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"]
**Explanation:** The first transaction is invalid because the second transaction occurs within a difference of 60 minutes, have 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"]
Example 3:
**Input:** transactions = ["alice,20,800,mtv","bob,50,1200,mtv"]
**Output:** ["bob,50,1200,mtv"]
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
.
