<p>You are given two arrays <code>nums1</code> and <code>nums2</code> consisting of positive integers.</p>

<p>You have to replace <strong>all</strong> the <code>0</code>&#39;s in both arrays with <strong>strictly</strong> positive integers such that the sum of elements of both arrays becomes <strong>equal</strong>.</p>

<p>Return <em>the <strong>minimum</strong> equal sum you can obtain, or </em><code>-1</code><em> if it is impossible</em>.</p>

<p>&nbsp;</p>
<p><strong class="example">Example 1:</strong></p>

<pre>
<strong>Input:</strong> nums1 = [3,2,0,1,0], nums2 = [6,5,0]
<strong>Output:</strong> 12
<strong>Explanation:</strong> We can replace 0&#39;s in the following way:
- Replace the two 0&#39;s in nums1 with the values 2 and 4. The resulting array is nums1 = [3,2,2,1,4].
- Replace the 0 in nums2 with the value 1. The resulting array is nums2 = [6,5,1].
Both arrays have an equal sum of 12. It can be shown that it is the minimum sum we can obtain.
</pre>

<p><strong class="example">Example 2:</strong></p>

<pre>
<strong>Input:</strong> nums1 = [2,0,2,0], nums2 = [1,4]
<strong>Output:</strong> -1
<strong>Explanation:</strong> It is impossible to make the sum of both arrays equal.
