3467. Transform Array by Parity

You are given an integer array nums. Transform nums by performing the following operations in the exact order specified:

1. Replace each even number with 0.
2. Replace each odd numbers with 1.
3. Sort the modified array in non-decreasing order.

Return the resulting array after performing these operations.

c++

class Solution {
public:
    vector<int> transformArray(vector<int>& nums) {
        for(int i = nums.size() - 1, odd = nums.size() - 1; i >= 0; i--) {
            if(nums[i] &= 1) swap(nums[i], nums[odd--]);
        }
        return nums;
    }
};
