**number of distinct ways**you can buy some number of pens and pencils.**Example 1:**

Input:total = 20, cost1 = 10, cost2 = 5Output:9Explanation:The price of a pen is 10 and the price of a pencil is 5. - If you buy 0 pens, you can buy 0, 1, 2, 3, or 4 pencils. - If you buy 1 pen, you can buy 0, 1, or 2 pencils. - If you buy 2 pens, you cannot buy any pencils. The total number of ways to buy pens and pencils is 5 + 3 + 1 = 9.

**Example 2:**

Input:total = 5, cost1 = 10, cost2 = 10Output:1Explanation:The price of both pens and pencils are 10, which cost more than total, so you cannot buy any writing utensils. Therefore, there is only 1 way: buy 0 pens and 0 pencils.
