#100The 3n + 1 problem

Given the input 22, the following sequence of numbers will be printed:

$22, 11, 34, 17, 52, 26, 13, 40, 20, 10, 5, 16, 8, 4, 2, 1$

It is conjectured that the algorithm above will terminate (when a 1 is printed) for any integral input value. Despite the simplicity of the algorithm, it is unknown whether this conjecture is true. It has been verified, however, for all integers $n$ such that $0 < n < 1{,}000{,}000$ (and, in fact, for many more numbers than this).

Given an input $n$, it is possible to determine the number of numbers printed before and including the 1 is printed. For a given $n$ this is called the cycle-length of $n$. In the example above, the cycle length of 22 is 16.

For any two numbers $i$ and $j$ you are to determine the maximum cycle length over all numbers between and including both $i$ and $j$.

Input

The input will consist of a series of pairs of integers $i$ and $j$, one pair of integers per line. All integers will be less than 10,000 and greater than 0.

You should process all pairs of integers and for each pair determine the maximum cycle length over all integers between and including $i$ and $j$. You can assume that no operation overflows a 32-bit integer.

Output

For each pair of input integers $i$ and $j$ you should output $i$, $j$, and the maximum cycle length for integers between and including $i$ and $j$. These three numbers should be separated by at least one space with all three numbers on one line and with one line of output for each line of input. The integers $i$ and $j$ must appear in the output in the same order in which they appeared in the input and should be followed by the maximum cycle length (on the same line).
