The Antique Comedians of Malidinesia play an interesting comedy where many animals occur. Because they want their plays to be as true as possible, a specialist studies the behaviour of various animals. Recently, he is interested in a binary dynamic ecological system hares-foxes (SHF). As a part of this project, you are asked to design and implement intelligent automatic target evaluation simulator (IATES) for this system. The behaviour of the SHF follows so called standard model, described by the following set of difference equations.

h_y+1 = a.h_y - b.f_y
f_y+1 = c.f_y + d.h_y

where h_y resp. f_y represent the difference of the number of hares resp. foxes in year _y and the reference count determined at the beginning of the experiment. The units of h_y and f_y are unknown. Therefore, h_y and f_y are to be treated as real numbers. Your task is to write a program to determine the long term evolution of SHF.

Input

The input consists of N cases (equal to about 5000). The first line of the input contains only positive integer N. Then follow the cases. Each case consists of six real numbers a, b, c, d, h₁₉₉₈ and f₁₉₉₈, written in this order on three lines, two numbers per line, separated by one or more spaces. The numbers are given in the classical format, i.e. optional sign, sequence of digits, optional dot and optional sequence of digits. The text form of a number does not exceed 10 characters. Each case is followed by one empty line.

Output

For each case, print one of the following sentences:

Example

Sample input:

2
2 0.5
0.5 0.6
2 3

0.1 1 
2 0.1
1 1

Sample output:

Both hares and foxes will overgrow.
Hares will die out while foxes will overgrow.
