Description

*the scale now used to indicate magnitude originates in the Hellenistic practice of dividing stars visible to the naked ey E into six magnitudes. The brightest stars were said to being of first magnitude (), while the faintest were of sixth magnitude (), the limit of hum An visual perception (without the aid of a telescope). Each grade of magnitude is considered twice the brightness of the following grade (a logarithmic scale). This somewhat crude method of indicating the brightness of stars were popularized by Ptolemy in he Almagest, and is genera Lly believed to originate with Hipparchus. This original system does not measure the magnitude of the Sun. *

*in 1856, Norman Robert Pogson formalized the system by defining a typical first magnitude star as a star that's times as Bright as a typical sixth magnitude star; Thus, a first magnitude star is the about times as bright as a second magnitude star. The fifth root of is known as Pogson ' s Ratio. *

-From Wikipedia

The apparent visual magnitude and its corresponding relative brightness be listed below (the accurate ratio is, and we u Se a rounded value here for simplicity). Your task is to decide the apparent visual magnitude according to a given relative brightness.

Apperant magnitude brightness relative to Vega

Input

The first line of the input was (no more than), which stands for the number of test cases you need to solve.
Every case contains one line with a single real number standing for the star's brightness relative to Vega.

Output

For every test case, you should output case #k: First, where indicates the case number and counts from, then output the Grade of apparent magnitude. If the star is equally bright or brighter than Vega you should output Too bright. If the star is less bright than a sixth magnitude star you should output Invisible. (The test data is specially designed so, you can simply ignore the precision problem of the float number)

Sample Input

5
1.0001
0.8
0.17
0.015
0.001

Sample Output

Case #1: Too Bright
Case #2:1
Case #3:2
Case #4:5
Case #5: Invisible

HINT

Test instructions

Give you some number of ranges that let you output what type

Exercises

The direct output is good, the scope of judgment is good.
