You start with an initial account balance of $100$.

You are given an integer purchaseAmount representing the cost of an item you want to buy.

When making the purchase, the amount charged is rounded to the nearest multiple of $10$. If purchaseAmount is equidistant between two multiples of $10$, it is rounded up to the greater multiple of $10$.

Return an integer representing your remaining account balance after paying the rounded amount.

Constraints:

• $0 \leq$ purchaseAmount $\leq 100$
