You are given a 1-indexed array of distinct integers nums
of length n
.
You need to distribute all the elements of nums
between two arrays arr1
and arr2
using n
operations. In the first operation, append nums[1]
to arr1
. In the second operation, append nums[2]
to arr2
. Afterwards, in the ith
operation:
arr1
is greater than the last element of arr2
, append nums[i]
to arr1
. Otherwise, append nums[i]
to arr2
.The array result
is formed by concatenating the arrays arr1
and arr2
. For example, if arr1 == [1,2,3]
and arr2 == [4,5,6]
, then result = [1,2,3,4,5,6]
.
Return the array result
.
\n
Example 1:
\n\n\nInput: nums = [2,1,3]\nOutput: [2,3,1]\nExplanation: After the first 2 operations, arr1 = [2] and arr2 = [1].\nIn the 3rd operation, as the last element of arr1 is greater than the last element of arr2 (2 > 1), append nums[3] to arr1.\nAfter 3 operations, arr1 = [2,3] and arr2 = [1].\nHence, the array result formed by concatenation is [2,3,1].\n\n\n
Example 2:
\n\n\nInput: nums = [5,4,3,8]\nOutput: [5,3,4,8]\nExplanation: After the first 2 operations, arr1 = [5] and arr2 = [4].\nIn the 3rd operation, as the last element of arr1 is greater than the last element of arr2 (5 > 4), append nums[3] to arr1, hence arr1 becomes [5,3].\nIn the 4th operation, as the last element of arr2 is greater than the last element of arr1 (4 > 3), append nums[4] to arr2, hence arr2 becomes [4,8].\nAfter 4 operations, arr1 = [5,3] and arr2 = [4,8].\nHence, the array result formed by concatenation is [5,3,4,8].\n\n\n
