Test on array methods/ array

Return an array that contains exactly the same numbers as the given array, but rearranged so that every 3 is immediately followed by a 4. Do not move the 3's, but every other number may move. The array contains the same number of 3's and 4's, every 3 has a number after it that is not a 3 or 4, and a 3 appears in the array before any 4. fix34({1, 3, 1, 4}) → {1, 3, 4, 1} fix34({1, 3, 1, 4, 4, 3, 1}) → {1, 3, 4, 1, 1, 3, 4} fix34({3, 2, 2, 4}) → {3, 4, 2, 2}, 2}
