Problem Statement

翻译中…

Determine if there exists a sequence obtained by permuting $1,2,...,N$ that satisfies the following conditions:

翻译中…
  • The length of its longest increasing subsequence is $A$.
  • The length of its longest decreasing subsequence is $B$.
翻译中…

If it exists, construct one such sequence.

翻译中…

Note

翻译中…

A subsequence of a sequence $P$ is a sequence that can be obtained by extracting some of the elements in $P$ without changing the order.

翻译中…

A longest increasing subsequence of a sequence $P$ is a sequence with the maximum length among the subsequences of $P$ that are monotonically increasing.

翻译中…

Similarly, a longest decreasing subsequence of a sequence $P$ is a sequence with the maximum length among the subsequences of $P$ that are monotonically decreasing.

Constraints

翻译中…
  • $1 \leq N,A,B \leq 3\times 10^5$
  • All input values are integers.
翻译中…

Input

翻译中…

Input is given from Standard Input in the following format:

翻译中…

N A B

翻译中…

Output

翻译中…

If there are no sequences that satisfy the conditions, print -1.

翻译中…

Otherwise, print $N$ integers. The $i$-th integer should be the $i$-th element of the sequence that you constructed.
