Given an array of integers `nums`, sort the array in ascending order and return it. You must solve the problem without using any built-in functions in `O(nlog(n))` time complexity and with the smallest space complexity possible. ### Example 1: **Input:** `nums = [5,2,3,1]` **Output:** `[1,2,3,5]` **Explanation:** After sorting the array, the positions of some numbers are not changed (for example, 2 and 3), while the positions of other numbers are changed (for example, 1 and 5). ### Example 2: **Input:** `nums = [5,1,1,2,0,0]` **Output:** `[0,0,1,1,2,5]` **Explanation:** Note that the values of nums are not necessairly unique. ### Constraints: * `1 <= nums.length <= 5 * 104` * `-5 * 104 <= nums[i] <= 5 * 104`

You are given a dataset with a significant class imbalance (e.g., 95% of the data belongs to class A, and 5% belongs to class B). Design a strategy to train a classification model that performs well on both classes. Discuss techniques to handle the imbalance, such as sampling methods, cost-sensitive learning, or evaluation metrics that should be prioritized. Assume the dataset contains 10,000 samples, and the model will be evaluated on a separate test set.
