Gwen loves most numbers. In fact, she loves every number that is not a multiple of $n$ (she really hates the number $n$). For her friends' birthdays this year, Gwen has decided to draw each of them a sequence of $n-1$ flowers. Each of the flowers will contain between $1$ and $n-1$ flower petals (inclusive). Because of her hatred of multiples of $n$, the total number of petals in any non-empty contiguous subsequence of flowers cannot be a multiple of $n$. For example, if $n = 5$, then the top two paintings are valid, while the bottom painting is not valid since the second, third and fourth flowers have a total of $10$ petals. (The top two images are Sample Input $3$ and $4$.)
Gwen wants her paintings to be unique, so no two paintings will have the same sequence of flowers. To keep track of this, Gwen recorded each painting as a sequence of $n-1$ numbers specifying the number of petals in each flower from left to right. She has written down all valid sequences of length $n-1$ in lexicographical order. A sequence $a_1,a_2,\dots, a_{n-1}$ is lexicographically smaller than $b_1, b_2, \dots, b_{n-1}$ if there exists an index $k$ such that $a_i = b_i$ for $i < k$ and $a_k < b_k$.
What is the $k$th sequence on Gwen's list?
The input consists of a single line containing two integers $n$ ($2 \leq n \leq 1\,000$), which is Gwen's hated number, and $k$ ($1 \leq k \leq 10^{18}$), which is the index of the valid sequence in question if all valid sequences were ordered lexicographically. It is guaranteed that there exist at least $k$ valid sequences for this value of $n$.
Display the $k$th sequence on Gwen's list.
