Find the number of palindromic numbers among the integers between A and B (inclusive). Here, a palindromic number is a positive integer whose string representation in base 10 (without leading zeros) reads the same forward and backward.
Constraints
* 10000 \leq A \leq B \leq 99999
* All input values are integers.
Input
Input is given from Standard Input in the following format:

Try guessing the statement from this picture <http://tiny.cc/ogyoiz>.
You are given two integers A and B, calculate the number of pairs (a, b) such that 1 ≤ a ≤ A, 1 ≤ b ≤ B, and the equation a ⋅ b + a + b = conc(a, b) is true; conc(a, b) is the concatenation of a and b (for example, conc(12, 23) = 1223, conc(100, 11) = 10011). a and b should not contain leading zeroes.
Input
The first line contains t (1 ≤ t ≤ 100) — the number of test cases.
Each test case contains two integers A and B (1 ≤ A, B ≤ 10^9).
Output
Print one integer — the number of pairs (a, b) such that 1 ≤ a ≤ A, 1 ≤ b ≤ B, and the equation a ⋅ b + a + b = conc(a, b) is true.

Note
There is only one suitable pair in the first test case: a = 1, b = 9 (1 + 9 + 1 ⋅ 9 = 19).
