1927：Area in Triangle
题目描述
Given a triangle field and a rope of a certain length (Figure-1), you are required to use the rope to enclose a region within the field and make the region as large as possible.
输入解释
The input has several sets of test data. Each set is one line containing four numbers separated by a space. The first three indicate the lengths of the edges of the triangle field, and the fourth is the length of the rope. Each of the four numbers have exactly four digits after the decimal point. The line containing four zeros ends the input and should not be processed. You can assume each of the edges are not longer than 100.0000 and the length of the rope is not longer than the perimeter of the field.
输出解释
Output one line for each case in the following format:
Case i: X
Where i is the case number, and X is the largest area which is rounded to two digits after the decimal point.
Case i: X
Where i is the case number, and X is the largest area which is rounded to two digits after the decimal point.
