Given a non-empty array
nums containing only positive integers, find if the array can be partitioned into two subsets such that the sum of elements in both subsets is equal.
Input: nums = [1,5,11,5] Output: true Explanation: The array can be partitioned as [1, 5, 5] and .
Input: nums = [1,2,3,5] Output: false Explanation: The array cannot be partitioned into equal sum subsets.
1 <= nums.length <= 200
1 <= nums[i] <= 100
