BMI (Body Mass Index, or BMI, English for Body Mass Index, or BMI), is to use weight in kilograms divided by height in meters square of the number, the Body Mass Index (BMI) ^ 2=weight (kg) present height (m), are commonly used to measure the degree of Body fat and a standard, whether health adults with a normal BMI between 18.5 to 23.9, so when BMI is greater than 23.9, for health is the time to lose weight!
Please define a class People, member variables defined in the class integer myWeight, members of the floating-point variables myHeight, myBMI etc., and define a member function calculateBMI () to calculate everyone's BMI, define a member function getAnswer () to determine whether need to lose weight,
Have multiple sets of data input, each person's weight (/kg), height (/m), please calculate his BMI, and whether he needs to lose weight, if need be, output "Yes!" , otherwise output "No!" Output (not including the quotes),

Input
Multiple sets of input, the two Numbers in each group on behalf of someone's weight and height,,
The Output
If you want to lose weight is output Yes! , there is No need to print the No! ,

The Sample Input
50 1.65
70
1.8080
1.75The Sample Output
No!
No!
Yes!
