Solve the programming task below in a Python markdown code block.
Given an alphanumeric string made up of digits and lower case Latin characters only, find the sum of all the digit characters in the string.

------ Input ------ 

The first line of the input contains an integer T denoting the number of test cases. Then T test cases follow.
Each test case is described with a single line containing a string S, the alphanumeric string.

------ Output ------ 

For each test case, output a single line containing the sum of all the digit characters in that string.

------ Constraints ------ 

$1 ≤ T ≤ 1000$
$1 ≤ |S| ≤ 1000, where |S| is the length of the string S.$

----- Sample Input 1 ------ 
1
ab1231da

----- Sample Output 1 ------ 
7
----- explanation 1 ------ 
The digits in this string are 1, 2, 3 and 1. Hence, the sum of all of them is 7.
