XGBoost Implementation
In this problem, you will implement a basic XGBoost algorithm using NumPy. XGBoost is an extension of gradient boosting that uses a regularized objective function to prevent overfitting.
**Example:** Suppose we have a dataset of patients with features such as age, sex, and disease status. We can use XGBoost to predict the disease status based on the features.
**Constraints:** You must use NumPy to perform the calculations.
Write a function that takes in the dataset and returns the predicted disease status.
