To celebrate the start of spring, Farmer John's $N$ cows ($1 \leq N \leq 2 \cdot 10^5$) have invented an intriguing new dance, where they stand in a circle and re-order themselves in a predictable way.

Specifically, there are $N$ positions around the circle, numbered sequentially from $0$ to $N-1$, with position $0$ following position $N-1$. A cow resides at each position. The cows are also numbered sequentially from $0$ to $N-1$. Initially, cow $i$ starts in position $i$. You are told a set of $K$ positions $0=A_1<A_2< \ldots< A_K<N$ that are "active", meaning the cows in these positions are the next to move ($1 \leq K \leq N$).

In each minute of the dance, two things happen. First, the cows in the active positions rotate: the cow at position $A_1$ moves to position $A_2$, the cow at position $A_2$ moves to position $A_3$, and so on, with the cow at position $A_K$ moving to position $A_1$. All of these $K$ moves happen simultaneously, so the after the rotation is complete, all of the active positions still contain exactly one cow. Next, the active positions themselves shift: $A_1$ becomes $A_1+1$, $A_2$ becomes $A_2+1$, and so on (if $A_i = N-1$ for some active position, then $A_i$ circles back around to $0$).

Please calculate the order of the cows after $T$ minutes of the dance ($1\le T\le 10^9$).

#### INPUT FORMAT (input arrives from the terminal / stdin):

The first line contains three integers $N$, $K$, and $T$.The second line contains $K$ integers representing the initial set of active positions $A_1,A_2, \ldots A_K$. Recall that $A_1 = 0$ and that these are given in increasing order.

#### OUTPUT FORMAT (print output to the terminal / stdout):

Output the order of the cows after $T$ minutes, starting with the cow in position $0$, separated by spaces.#### SAMPLE INPUT:

5 3 4 0 2 3

#### SAMPLE OUTPUT:

1 2 3 4 0

For the example above, here are the cow orders and $A$ for the first four timesteps:

Initial, T = 0: order = [0 1 2 3 4], A = [0 2 3] T = 1: order = [3 1 0 2 4] T = 1: A = [1 3 4] T = 2: order = [3 4 0 1 2] T = 2: A = [2 4 0] T = 3: order = [2 4 3 1 0] T = 3: A = [3 0 1] T = 4: order = [1 2 3 4 0]

#### SCORING:

- Inputs 2-7: $N \leq 1000, T \leq 10000$
- Inputs 8-13: No additional constraints.
