VPL2_AA  Luis Quest
Luis is playing his old metroid game. Just a little while ago he pass trough a scenario where the room was filled with some amoebalike creatures. The room started with some initial number of creatures, but they multiply their selves very quickly, because their growth rate is proportional to the number of creatures at a certain time. Luis took note about this fact, he wrote the number of creatures at the initial time, and then, after wait t time units, he wrote the new amount. Now Luis wants to know, for a certain number of creatures p, the exact time he has to be in the room to see that amount.
Input
The first line contains an integer T, which specifies the number of test cases. Then, will follow the descriptions of T test cases.
For each test case, there will be 2 lines, the first one will contain 4 integers, p0, p1, t and p. These numbers represents the initial amount of creatures, the second amount of creatures, the time units that Luis waited to see that change, and the number of creatures that Luis wants to see.
Output
For each input case you must print a single line containing the string "Scenario #i: " where i is the number of the test case (starting at one), and then the answer to the problem rounded to two decimal places. There will always be an answer.
Example
Input: 4 10 15 3 15 10 15 3 20 5 12 2 50 5 12 2 7 Output: Scenario #1: 3.00 Scenario #2: 5.13 Scenario #3: 5.26 Scenario #4: 0.77
Constraints  100%
1 ≤ T, p0, p1, t, p ≤ 100

Use double!! Float cost me 2 WAs

using double gave me AC...instead of float
