In C language please! You are given an integer array banned and two integers n and maxSum. You are choosing some number of integers following the below rules: ● The chosen integers have to be in the range [1, n]. ● Each integer can be chosen at most once. ● The chosen integers should not be in the array banned. ● The sum of the chosen integers should not exceed maxSum. Return the maximum number of integers you can choose following the mentioned rules Constraint: ● 1 <= banned.length <= 10^4 ● 1 <= banned [i], n <= 10^4 ● 1 <= maxSum <= 10^9 Example 1: Input: banned = [1,2,3,4,5,6,7], n = 8, maxSum = 1 Output: 0 Reason: You cannot choose any integer while following the mentioned conditions. Example 2: Input: banned = [1,6,5], n = 5, maxSum = 6 Output: 2 Reason:.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 3: Input: banned = [11], n = 7, maxSum = 50 Output: -7 Reason: 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.

In C language please! You are given an integer array banned and two integers n and maxSum. You are choosing some number of integers following the below rules:

● The chosen integers have to be in the range [1, n].

● Each integer can be chosen at most once.

● The chosen integers should not be in the array banned.

● The sum of the chosen integers should not exceed maxSum.

Return the maximum number of integers you can choose following the mentioned rules Constraint:

● 1 <= banned.length <= 10^4

● 1 <= banned [i], n <= 10^4

● 1 <= maxSum <= 10^9

Example 1:

Input: banned = [1,2,3,4,5,6,7], n = 8, maxSum = 1

Output: 0

Reason: You cannot choose any integer while following the mentioned conditions.

Example 2:

Input: banned = [1,6,5], n = 5, maxSum = 6

Output: 2

Reason:.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 3:

Input: banned = [11], n = 7, maxSum = 50

Output: -7

Reason: 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.
