You are given a permutation $P$ of $1, 2, \cdots, N$. You can divide $P$ into exactly $K$ non-empty contiguous subsequences as you like. Maroon will rearrange those subsequences you make and concatenate them to make a new permutation $Q$. Here, he will lexicographically maximize $Q$. You want to divide $P$ in a way that lexicographically minimizes $Q$. Find $Q$ in that case. ## Constraints * $1 \leq N \leq 2 \times 10^5$ * $1 \leq K \leq N$ * $1 \leq P_i \leq N$ * $P_i \neq P_j (i \neq j)$ * All values in input are integers. ## Input Input is given from Standard Input in the following format: $N$ $K$ $P_1$ $P_2$ $\cdots$ $P_N$ [samples]
Samples
Input #1
3 2
1 2 3
Output #1
2 3 1

You have two ways to divide $P$: $(1, 2),(3)$ and $(1), (2, 3)$.
In the former case, Maroon will rearrange them in the order $(3), (1, 2)$ to get $Q = (3, 1, 2)$.
In the latter case, Maroon will rearrange them in the order $(2, 3), (1)$ to get $Q = (2, 3, 1)$.
Thus, you should choose the latter.
Input #2
4 3
