9225: ABC290 —— D - Marking
[Creator : ]
Description
### Problem Statement
There are $N$ squares indexed $0$ through $(N-1)$ arranged in a line. Snuke is going to mark every square by the following procedure.
1. Mark square $0$.
2. Repeat the following steps i - iii $(N-1)$ times.
1. Initialize a variable $x$ with $(A+D) \bmod N$, where $A$ is the index of the square marked last time.
2. While square $x$ is marked, repeat replacing $x$ with $(x+1) \bmod N$.
3. Mark square $x$.
Find the index of the square that Snuke marks for the $K$-th time.
Given $T$ test cases, find the answer for each of them.

If N=4 and D=2, Snuke marks the squares as follows.
- Mark square 0.
-
(1-st iteration) Let x=(0+2) mod 4=2. Since square 2 is not marked, mark it.
(2-nd iteration) Let x=(2+2) mod 4=0. Since square 0 is marked, let x=(0+1) mod 4=1. Since square 1 is not marked, mark it.
(3-rd iteration) Let x=(1+2) mod 4=3. Since square 3 is not marked, mark it.
