Max Sequence II
Given N real numbers a1, a2, …, aN, you are to write a program to calculate P as defined below.
The input consists of several test cases. Each test case consists of two lines:
For each test case, output P in scientific notation in a single line. If P is equal to zero, output “0.000”. If 1 ≤ |P| < 10, output P directly with its fractional part rounded to three decimal places. In any other cases, output P in the format xEn where P = x × 10n (1 ≤ |x| < 10 and n is an integer). x should also be rounded to three digits after decimal point.
5 -5.0 2.0 3.0 -2.0 0.5 3 -1 0 -1
Built-in floating-point types provided by the compilers may not hold P.
