The Fibonacci sequence is a set of numbers that starts with a zero, followed by a one, and proceeds based on the rule that, each number (called a Fibonacci number) is equal to the sum of the previous two numbers. If the Fibonacci sequence is denoted F(n), where n is the term in the sequence,

Now your task is to find the total number of odd Fibonacci numbers and total number of even Fibonacci numbers between a range (consider 0 as an even number).

Input

First Line of the input contains T, representing the number of test case (1 ≤ T ≤ 50). For each test case contains two integers N and M where (1 ≤ N ≤ 10¹⁸) and (1 ≤ M ≤ 10¹⁸).

Output

You have to calculate total number of odd Fibonacci numbers and total number of even Fibonacci numbers between N^th Fibonacci number and M^th Fibonacci number.

For each test case print case number with the desire answer as show sample output.

Example

Input:
2
2 6
1 5

Output:
Case 1:
Odd = 4
Even = 1
Case 2:
Odd = 3
Even = 2
