A transaction is possibly invalid if:
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.
