Problem statement

Given an array and a range [lowVal, highVal], partition the array into three parts:

All elements smaller than lowVal come first.
All elements in the range [lowVal, highVal] come next.
All elements greater than highVal come last.

Additionally: If lowVal and highVal exist in the array, ensure that lowVal appears before highVal in the final result. The relative order of elements within each group doesn't matter.

Function

threePartitionArray(arr: int[], lowVal: int, highVal: int) → int[]

Complete the function threePartitionArray in the editor.

threePartitionArray has the following parameters:

int arr[]: an array of integers
int lowVal: an integer representing the lower bound of the range
int highVal: an integer representing the upper bound of the range
