The Body Mass Index (BMI) is one of the calculations used by doctors to assess an adult's health. The doctor measures the patient's height (in metres) and weight (in kilograms), then calculates the BMI using the formula:

$$\displaystyle BMI = \frac{weight}{height \times height}$$

Write a program which takes the patient's weight and height as input, calculates the BMI, and displays the corresponding message from the table below.

BMI Category	Message
More than ~25~	Overweight
Between ~18.5~ and ~25.0~ (inclusive)	Normal weight
Less than ~18.5~	Underweight

Sample Input 1

69
1.73

Output for Sample Input 1

Normal weight

Explanation of Output for Sample Input 1

The BMI is ~\frac{69}{1.73 \times 1.73}~ which is approximately ~23.0545~. According to the table, this is a "Normal weight".

Sample Input 2

84.5
1.8

Output for Sample Input 2

Overweight

Explanation of Output for Sample Input 2

The BMI is ~\frac{84.5}{1.8 \times 1.8}~, which is approximately ~26.0802~. According to the table, this is "Overweight".
