You are given an integer array `coins`

of length `n`

which represents the `n`

coins that you own. The value of the `i`

coin is ^{th}`coins[i]`

. You can **make** some value `x`

if you can choose some of your `n`

coins such that their values sum up to `x`

.

Return the *maximum number of consecutive integer values that you can make with your coins starting from and including *

`0`

.Note that you may have multiple coins of the same value.

**Example 1:**

Input:coins = [1,3]Output:2Explanation:You can make the following values: - 0: take [] - 1: take [1] You can make 2 consecutive integer values starting from 0.

**Example 2:**

Input:coins = [1,1,1,4]Output:8Explanation:You can make the following values: - 0: take [] - 1: take [1] - 2: take [1,1] - 3: take [1,1,1] - 4: take [4] - 5: take [4,1] - 6: take [4,1,1] - 7: take [4,1,1,1] You can make 8 consecutive integer values starting from 0.

**Example 3:**

Input:nums = [1,4,10,3,1]Output:20

**Constraints:**

`coins.length == n`

`1 <= n <= 4 * 10`

^{4}`1 <= coins[i] <= 4 * 10`

^{4}
