Given an integer array nums, return a new array with a length of nums.length*3 where each element in nums appears three times in a row.


tripleElements([2, 3, 5, 4]) → [2, 2, 2, 3, 3, 3, 5, 5, 5, 4, 4, 4]
tripleElements([1, 2, 2, 3, 4, 4, 5, 6]) → [1, 1, 1, 2, 2, 2, 2, 2, 2, 3, 3, 3, 4, 4, 4, 4, 4, 4, 5, 5, 5, 6, 6, 6]
tripleElements([1, 2, 3, 4, 5, 6]) → [1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 6, 6, 6]
