Define a class to overload the method print() as follows:
void print() – To print the given format using nested loops.

@#@#@
@#@#@
@#@#@
@#@#@

double print(double a, double b) – To display the sum of numbers between a and b with difference of 0.5.
e.g. if a = 1.0, b = 4.0
Output is: 1.0 + 1.5 + 2.0 + 2.5 + … + 4.0
int print(char ch1, char ch2) – Compare the two characters and return the ASCII code of the largest character.
