Find out the maximum sub-array of non negative numbers from an array.

The sub-array should be contiguous i.e., a sub-array created by choosing the second and fourth element and skipping the third element is invalid.

Maximum sub-array is defined in terms of the sum of the elements in the sub-array. Sub-array **A** is greater than sub-array **B** if **sum(A) > sum(B)**.

Example:

A : [1, 2, 5, -7, 2, 3]

The two sub-arrays are [1, 2, 5] [2, 3].

The answer is [1, 2, 5] as its sum is larger than [2, 3]

**NOTE 1**: If there is a tie, then compare with segment's length and return segment which has maximum length.

**NOTE 2**: If there is still a tie, then return the segment with minimum starting index.

**Example 1:**

**Input:
**N = 3
A[] = {1, 2, 3}
**Output:** 1 2 3
**Explanation:** In the given array every
element is non-negative.

**Example 2:**

**Input:
**N = 2
A[] = {-1, 2}
**Output:** 2
**Explanation:** The only subarray [2] is
the answer.

**Your Task:**

Complete the function **findSubarray()** which takes the array **a** and the size of the array, **n**, as input parameters and returns an array representing the answer. If there is no subarray return an array of length **1** containing **-1** only. You don't to print answer or take inputs.

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

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

**Constraints:**

1 ≤ N ≤ 10^{5}

-10^{5 }≤ A[i] ≤ 10^{5}
