Examples

Example 1
INPUT
banned = [1,6,5], n = 5, maxSum = 6
OUTPUT
2
EXPLANATION

You can choose the integers 2 and 4. 2 and 4 are from the range [1, 5], both did not appear in banned, and their sum is 6, which did not exceed maxSum.

Example 2
INPUT
banned = [1,2,3,4,5,6,7], n = 8, maxSum = 1
OUTPUT
0
EXPLANATION

You cannot choose any integer while following the mentioned conditions.

Example 3
INPUT
banned = [11], n = 7, maxSum = 50
OUTPUT
7
EXPLANATION

You can choose the integers 1, 2, 3, 4, 5, 6, and 7. They are from the range [1, 7], all did not appear in banned, and their sum is 28, which did not exceed maxSum.

Constraints

1 <= banned.length <= 104
1 <= banned[i], n <= 104
1 <= maxSum <= 109
