Railways#355
Two railways intersect at right angles. The origin is at their intersection point, and the coordinate axes coincide with the rails. To prevent accidents at the intersection, a dispatcher is assigned, but, as often happens, he fell asleep at work. During this time, two trains are moving towards each other along different tracks. The speeds of the trains, their lengths, and the initial coordinates of the "head" of each train are known. The initial coordinates are positive.
Determine whether a disaster will occur.
First, the number of test cases (T \leq 10) is given. Then, for each test, there are real numbers: V_1 — the speed of the first train, V_2 — the speed of the second train, L_1 — the length of the first train, L_2 — the length of the second train, X_1, Y_1 — the coordinates of the "head" of the first train, X_2, Y_2 — the coordinates of the "head" of the second train. All numbers do not exceed and are given in one line separated by spaces.
For each test case, print if a disaster occurs, and if everything is fine. All answers must be printed in one line without spaces between them, and there should be no spaces at the beginning or at the end of the line. If the "head" of one train just touches the "tail" of the other, consider that only a slight scare occurred, and print .
