#D10714. Rabbit Exercise
Rabbit Exercise
Rabbit Exercise
There are N rabbits on a number line. The rabbits are conveniently numbered 1 through N. The coordinate of the initial position of rabbit i is x_i.
The rabbits will now take exercise on the number line, by performing sets described below. A set consists of M jumps. The j-th jump of a set is performed by rabbit a_j (2≤a_j≤N-1). For this jump, either rabbit a_j-1 or rabbit a_j+1 is chosen with equal probability (let the chosen rabbit be rabbit x), then rabbit a_j will jump to the symmetric point of its current position with respect to rabbit x.
The rabbits will perform K sets in succession. For each rabbit, find the expected value of the coordinate of its eventual position after K sets are performed.
Constraints
- 3≤N≤10^5
- x_i is an integer.
- |x_i|≤10^9
- 1≤M≤10^5
- 2≤a_j≤N-1
- 1≤K≤10^{18}
Input
The input is given from Standard Input in the following format:
N x_1 x_2 ... x_N M K a_1 a_2 ... a_M
Output
Print N lines. The i-th line should contain the expected value of the coordinate of the eventual position of rabbit i after K sets are performed. The output is considered correct if the absolute or relative error is at most 10^{-9}.
