BMI Categorization

You are given a weight in kilograms and a height in meters. Your task is to calculate the Body Mass Index (BMI) using the formula:

\( \text{BMI} = \frac{\text{weight}}{(\text{height})^2} \)

Then, you should determine the BMI category according to the following criteria:

• Underweight: BMI < 18.5
• Normal weight: 18.5 ≤ BMI < 24.9
• Overweight: 24.9 ≤ BMI < 29.9
• Obesity: BMI ≥ 29.9

Print the corresponding category as a single line output.
