Polycarp has to solve exactly $n$ problems to improve his programming skill before an important programming competition. But this competition will be held very soon, most precisely, it will start in $k$ days. It means that Polycarp has exactly $k$ days for training!

Polycarp doesn't want to procrastinate, so he wants to solve at least one problem during each of $k$ days. He also doesn't want to overwork, so if he solves $x$ problems during some day, he should solve no more than $2x$ problems during the next day. And, at last, he wants to improve his skill, so if he solves $x$ problems during some day, he should solve at least $x+1$ problem during the next day.

More formally: let $[a_1, a_2, \dots, a_k]$ be the array of numbers of problems solved by Polycarp. The $i$-th element of this array is the number of problems Polycarp solves during the $i$-th day of his training. Then the following conditions must be satisfied:

• sum of all $a_i$ for $i$ from $1$ to $k$ should be $n$;
• $a_i$ should be greater than zero for each $i$ from $1$ to $k$;
• the condition $a_i < a_{i + 1} \le 2 a_i$ should be satisfied for each $i$ from $1$ to $k-1$.

Your problem is to find any array $a$ of length $k$ satisfying the conditions above or say that it is impossible to do it.

Input

The first line of the input contains two integers $n$ and $k$ ($1 \le n \le 10^9, 1 \le k \le 10^5$) — the number of problems Polycarp wants to solve and the number of days Polycarp wants to train.

Output

If it is impossible to find any array $a$ of length $k$ satisfying Polycarp's rules of training, print "NO" in the first line.

Otherwise print "YES" in the first line, then print $k$ integers $a_1, a_2, \dots, a_k$ in the second line, where $a_i$ should be the number of problems Polycarp should solve during the $i$-th day. If there are multiple answers, you can print any.
