Score : $500$ points
There are $N$ pieces on a two-dimensional plane. The coordinates of Piece $i$ are $(X_i,Y_i)$. There may be multiple pieces at the same coordinates.
We will do $M$ operations $\mathrm{op}_1, \ldots, \mathrm{op}_M$, one by one. There are four kinds of operations, described below along with their formats in input.
1
:Rotate every piece $90$ degrees clockwise about the origin;2
:Rotate every piece $90$ degrees counterclockwise about the origin;3 p
:Move each piece to the point symmetric to it about the line $x=p$;4 p
:Move each piece to the point symmetric to it about the line $y=p$.You are given $Q$ queries. In the $i$-th query, given two integers $A_i$ and $B_i$, print the coordinates of Piece $B_i$ just after the $A_i$-th operation. Here, the moment just before the $1$-st operation is considered to be the moment just after "the $0$-th operation".
3 p
or 4 p
, $-10^9 \leq p \leq 10^9$.Input is given from Standard Input in the following format:
$N$ $X_1$ $Y_1$ $\vdots$ $X_N$ $Y_N$ $M$ $\mathrm{op}_1$ $\vdots$ $\mathrm{op}_M$ $Q$ $A_1$ $B_1$ $\vdots$ $A_Q$ $B_Q$
Print the response to each query in its own line: the $x$- and $y$-coordinates, in this order, with space in between.
1 1 2 4 1 3 3 2 4 2 5 0 1 1 1 2 1 3 1 4 1
1 2 2 -1 4 -1 1 4 1 0
Initially, the only piece - Piece $1$ - is at $(1, 2)$. Each operation moves the piece as follows: $(1,2)\to(2,-1)\to(4,-1)\to(1,4)\to(1,0)$.
