You are given three integers $x, y$ and $n$. Your task is to find the maximum integer $k$ such that $0 \le k \le n$ that $k \bmod x = y$, where $\bmod$ is modulo operation. Many programming languages use percent operator % to implement it.

In other words, with given $x, y$ and $n$ you need to find the maximum possible integer from $0$ to $n$ that has the remainder $y$ modulo $x$.

You have to answer $t$ independent test cases. It is guaranteed that such $k$ exists for each test case.

The first line of the input contains one integer $t$ ($1 \le t \le 5 \cdot 10^4$) — the number of test cases. The next $t$ lines contain test cases.

The only line of the test case contains three integers $x, y$ and $n$ ($2 \le x \le 10^9;~ 0 \le y < x;~ y \le n \le 10^9$).

It can be shown that such $k$ always exists under the given constraints.

For each test case, print the answer — maximum non-negative integer $k$ such that $0 \le k \le n$ and $k \bmod x = y$. It is guaranteed that the answer always exists.
