Three real
numbers õ, y and z are given. Find min(max(x, y), max(y,
z), x + y + z) using the auxiliary
functions for calculation the minimum and the maximum of two elements.
Input. Three real numbers õ, ó and z are given in one line. Their values do not
exceed 100 by absolute value.
Output. Print the
answer with two decimal digits.

functions
Define the functions minimum and maximum of two numbers. Using
them compute the required expression.
Algorithm realization
Define
the functions minimum min and
maximum max of two numbers.
double min(double
x, double y)
{
return (x
< y) ? x : y;
}
double max(double
x, double y)
{
return (x
> y) ? x : y;
}
The main part of the program. Read the input data. Compute and print the
answer.
scanf("%lf %lf %lf",&x,&y,&z);
res =
min(min(max(x,y),max(y,z)),x+y+z);
printf("%.2lf\n",res);
