You are given three numbers $a$, $b$, $c$ . Write a program to determine the largest number that is less than or equal to $c$ and leaves a remainder $b$ when divided by $a$.

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow.
- Each testcase contains a single line of input, having three integers $a$, $b$, $c$.

-----Output:-----
- For each testcase, output in a single line the largest number less than or equal to $c$.

-----Constraints:-----
- $1 \leq T  \leq 100000$
- $0 \leq b < a < c \leq$ $10$^18

-----Sample Input:-----

7 2 10

-----Sample Output:-----
