1169. Invalid Transactions Medium

2 * [1169] Invalid Transactions
3 *
4 * A transaction is possibly invalid if:
5 * 
6 * 	the amount exceeds $1000, or;
7 * 	if it occurs within (and including) 60 minutes of another transaction with the same name in a different city.
8 * 
9 * 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.
10 * Return a list of transactions that are possibly invalid. You may return the answer in any order.
11 *  
12 * Example 1:
13 * 
14 * Input: transactions = ["alice,20,800,mtv","alice,50,100,beijing"]
15 * Output: ["alice,20,800,mtv","alice,50,100,beijing"]
16 * 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.
17 * Example 2:
18 * 
19 * Input: transactions = ["alice,20,800,mtv","alice,50,1200,mtv"]
20 * Output: ["alice,50,1200,mtv"]
21 * 
22 * Example 3:
23 * 
24 * Input: transactions = ["alice,20,800,mtv","bob,50,1200,mtv"]
25 * Output: ["bob,50,1200,mtv"]
26 * 
27 *  
28 * Constraints:
29 * 
30 * 	transactions.length <= 1000
31 * 	Each transactions[i] takes the form "{name},{time},{amount},{city}"
32 * 	Each {name} and {city} consist of lowercase English letters, and have lengths between 1 and 10.
33 * 	Each {time} consist of digits, and represent an integer between 0 and 1000.
34 * 	Each {amount} consist of digits, and represent an integer between 0 and 2000.
