Problem Statement

In Finite Encyclopedia of Integer Sequences (FEIS), all integer sequences of lengths between 1 and N (inclusive) consisting of integers between 1 and K (inclusive) are listed.

Let the total number of sequences listed in FEIS be X. Among those sequences, find the (X/2)-th (rounded up to the nearest integer) lexicographically smallest one.

Constraints

1 \leq N,K \leq 3 × 10^5

N and K are integers.

Input

Input is given from Standard Input in the following format:

K N

Output

Print the (X/2)-th (rounded up to the nearest integer) lexicographically smallest sequence listed in FEIS, with spaces in between, where X is the total number of sequences listed in FEIS.

Sample Input 1

3 2

Sample Output 1

2 1

There are 12 sequences listed in FEIS: (1),(1,1),(1,2),(1,3),(2),(2,1),(2,2),(2,3),(3),(3,1),(3,2),(3,3).
The (12/2 = 6)-th lexicographically smallest one among them is (2,1).

Sample Input 2

2 4

Sample Output 2

1 2 2 2

Sample Input 3

5 14

Sample Output 3

3 3 3 3 3 3 3 3 3 3 3 3 2 2

Solution in Python (3.4.3) (judge verdict: Accepted)

def main():
    K,N = map(int,input().split())

    if K % 2 == 0:
        ans = [K//2]
        for i in range(N-1):
            ans.append(K)
    else:
        back = N // 2
        mid = K // 2 + 1
        ans = [mid for i in range(N)]
        for i in range(back):
            if ans[-1] == 1:
                ans.pop()
            else:
                ans[-1] -= 1
                while len(ans) < N:
                    ans.append(K)
    print(' '.join(map(str, ans)))
