Given an array of size N, find the smallest positive integer value that cannot be represented as sum of some elements from the array.

**Example 1:**

**Input: **
N = 6
array[] = {1, 10, 3, 11, 6, 15}
**Output: **
2
**Explanation:**
2 is the smallest integer value that cannot
be represented as sum of elements from the array.

**Example 2:**

**Input: **
N = 3
array[] = {1, 1, 1}
**Output: **
4
**Explanation: **
1 is present in the array.
2 can be created by combining two 1s.
3 can be created by combining three 1s.
4 is the smallest integer value that cannot be
represented as sum of elements from the array.

**Your Task: **

You dont need to read input or print anything. Complete the function **smallestpositive() **which takes the array and N as input parameters and returns the smallest positive integer value that cannot be represented as sum of some elements from the array.

**Expected Time Complexity: **O(N * Log(N))

**Expected Auxiliary Space: **O(1)

**Constraints:**

1 ≤ N ≤ 10^{6}

1 ≤ array[i] ≤ 10^{9}

Array may contain duplicates.
