You are given an integer array nums of even length. You have to split the array into two parts nums1 and nums2 such that:

\n\n\n\n

Return true if it is possible to split the array, and false otherwise.

\n\n

 

\n

Example 1:

\n\n
\nInput: nums = [1,1,2,2,3,4]\nOutput: true\nExplanation: One of the possible ways to split nums is nums1 = [1,2,3] and nums2 = [1,2,4].\n
\n\n

Example 2:

\n\n
\nInput: nums = [1,1,1,1]\nOutput: false\nExplanation: The only possible way to split nums is nums1 = [1,1] and nums2 = [1,1]. Both nums1 and nums2 do not contain distinct elements. Therefore, we return false.\n
