You are given a 0-indexed integer array nums. For each index i (1 <= i <= nums.length - 2) the beauty of nums[i] equals:

\n\n\n\n

Return the sum of beauty of all nums[i] where 1 <= i <= nums.length - 2.

\n\n

 

\n

Example 1:

\n\n
\nInput: nums = [1,2,3]\nOutput: 2\nExplanation: For each index i in the range 1 <= i <= 1:\n- The beauty of nums[1] equals 2.\n
\n\n

Example 2:

\n\n
\nInput: nums = [2,4,6,4]\nOutput: 1\nExplanation: For each index i in the range 1 <= i <= 2:\n- The beauty of nums[1] equals 1.\n- The beauty of nums[2] equals 0.\n
\n\n

Example 3:

\n\n
\nInput: nums = [3,2,1]\nOutput: 0\nExplanation: For each index i in the range 1 <= i <= 1:\n- The beauty of nums[1] equals 0.\n
