Given an integer array `nums`, return `true` if you can partition the array into two subsets such that the sum of the elements in both subsets is equal or `false` otherwise.
Example 1
Input:nums = [1,5,11,5]
Output:true
Explanation:The array can be partitioned as [1, 5, 5] and [11].
Example 2
Input:nums = [1,2,3,5]
Output:false
Explanation:The array cannot be partitioned into equal sum subsets.
