Rearrange Array by Parity in Place | Dataford Interview Questions

Implement a function to separate even and odd numbers in an array, placing odd numbers on the left and even numbers on the right.

Use an in-place partitioning approach. The relative order within the odd and even groups does not need to be preserved. The function receives a list of integers and returns the same list after rearrangement.

Constraints

0 <= nums.length <= 10^4
-10^9 <= nums[i] <= 10^9
The rearrangement must be performed in place.
The relative order within either parity group does not need to be preserved.

Function Signature

def separate_odd_even(nums):
