Design Splitwise Application

Input

You can create a few users in your main method. No need to take user IDs as input.

There will be three types of input:

• Expense: Format: EXPENSE <user-id-of-person-who-paid> <no-of-users> <space-separated-list-of-users> <EQUAL/EXACT> <space-separated-values-in-case-of-non-equal>
• Show balances for all: SHOW
• Show balances for a single user: SHOW <user-id>

Output

When asked to show the balance for a single user, display all balances that user is part of.

Format: <user-id-of-x> owes <user-id-of-y>: <amount>

If there are no balances for the input, print "No balances".

In cases where the user for whom the balance was asked owes money, they will be represented as 'x'. They will be represented as 'y' otherwise.
