Problem Statement
Determine if there exists a sequence obtained by permuting $1,2,...,N$ that satisfies the following conditions:
- The length of its longest increasing subsequence is
$A$. - The length of its longest decreasing subsequence is
$B$.
If it exists, construct one such sequence.
Note
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.
A longest increasing subsequence of a sequence $P$ is a sequence with the maximum length among the subsequences of $P$ that are monotonically increasing.
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
$1 \leq N,A,B \leq 3\times 10^5$- All input values are integers.
Input
Input is given from Standard Input in the following format:
N A B
Output
If there are no sequences that satisfy the conditions, print -1.
Otherwise, print $N$ integers. The $i$-th integer should be the $i$-th element of the sequence that you constructed.
