Chef's son Chefu found some matches in the kitchen and he immediately starting playing with them.

The first thing Chefu wanted to do was to calculate the result of his homework — the sum of $A$ and $B$, and write it using matches. Help Chefu and tell him the number of matches needed to write the result.

Digits are formed using matches in the following way:

------  Input ------
The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
The first and only line of each test case contains two space-separated integers $A$ and $B$.

------  Output ------
For each test case, print a single line containing one integer — the number of matches needed to write the result ($A+B$).

------  Constraints ------
$1 ≤ T ≤ 1,000$
$1 ≤ A, B ≤ 10^{6}$

----- Sample Input 1 ------

123 234

10101 1010

----- Sample Output 1 ------ 
13

----- explanation 1 ------ 
Example case 1: The result is $357$. We need $5$ matches to write the digit $3$, $5$ matches to write the digit $5$ and $3$ matches to write the digit $7$.

Example case 2: The result is $11111$. We need $2$ matches to write each digit $1$, which is $2 \cdot 5 = 10$ matches in total.
