题目描述
Leo has developed a new programming language C+=. In C+=, integer variables can only be changed with a "+=" operation that adds the right-hand side value to the left-hand side variable. For example, performing "a += b" when a = $2$ , b = $3$ changes the value of a to $5$ (the value of b does not change).
In a prototype program Leo has two integer variables a and b, initialized with some positive values. He can perform any number of operations "a += b" or "b += a". Leo wants to test handling large integers, so he wants to make the value of either a or b strictly greater than a given value $n$ . What is the smallest number of operations he has to perform?

输入格式
The first line contains a single integer $T$ ( $1 \leq T \leq 100$ ) — the number of test cases.
Each of the following $T$ lines describes a single test case, and contains three integers $a, b, n$ ( $1 \leq a, b \leq n \leq 10^9$ ) — initial values of a and b, and the value one of the variables has to exceed, respectively.

输出格式
For each test case print a single integer — the smallest number of operations needed. Separate answers with line breaks.

输出 #1
2 7
说明/提示
In the first case we cannot make a variable exceed $3$ in one operation. One way of achieving this in two operations is to perform "b += a" twice.
