1169 - Invalid Transactions\. Medium 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`.
