Task

Determine the client's membership level based on the invested amount of money and the given thresholds for membership levels.

There are four membership levels (from highest to lowest): Platinum, Gold, Silver, Bronze

The minimum investment is the threshold limit for Bronze membership. If the given amount is less than the Bronze treshold limit return Not a member.

A client belongs to a membership level when his invested amount is greater than or equal the level's threshold amount.

Examples:

|--------+----------+------+--------+--------+--------------+------------------|
| Amount | Platinum | Gold | Silver | Bronze | Result       | Explanations     |
|--------+----------+------+--------+--------+--------------+------------------|
|   7000 |    10000 | 8000 |   6000 |   4000 | Silver       | Amount >= Silver |
|   3000 |    10000 | 8000 |   6000 |   5000 | Not a member | Amount < Bronze  |
|   8000 |    12000 | 8000 |   7000 |   5000 | Gold         | Amount >= Gold   |
|--------+----------+------+--------+--------+--------------+------------------|
