Invalid Transactions.py

# 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.

# Given a list of transactions, return a list of transactions that are possibly invalid.  You may return the answer in any order.

#transactions = ["alice,20,800,mtv","alice,50,100,beijing"]
