Problem Statement
For a sequence of integers $P = (P_1, \ldots, P_M)$, let f(P) denote the sequence obtained by inserting P_i + P_{i+1} between P_i and P_{i+1} for each $1\leq i\leq M-1$.
More formally:
- Let Q_i = P_i + P_{i+1} for each $1\leq i\leq M - 1$.
- Let f(P) be defined as a sequence of $2M-1 integers f(P) = (P_1, Q_1, P_2, Q_2, \ldots, P_{M-1}, Q_{M-1}, P_M)$.
Given are three positive integers a, b, and N where $a, b\leq N$. Let us begin with a sequence A = (a, b) and define $a sequence B = (B_1, B_2, \ldots)$ as follows.
- Do the following N times: replace A with f(A).
- Then, remove from A all values greater than N and let B be the resulting sequence.
Find $B_L, \ldots, B_R$.
Input
Input is given from Standard Input in the following format:
a b N
L R
Output
Print $a line containing B_L, \ldots, B_R$, with a space in between.
Constraints
- $1\leq N\leq 3\times 10^5$
- $1\leq a, b\leq N$
- $1\leq L\leq R\leq 10^{18}$
- $R - L < 3\times 10^5$
- R is at most the number of elements in the sequence B.
Sample Input 1
1 1 4
1 7
Sample Output 1
1 4 3 2 3 4 1
Initially, A = (1, 1). The replacements of A with f(A) take place as follows.
- After the first replacement: A = (1, 2, 1).
- After the second replacement: A = (1, 3, 2, 3, 1).
- After the third replacement: A = (1, 4, 3, 5, 2, 5, 3, 4, 1).
- After the fourth replacement: A = (1, 5, 4, 7, 3, 8, 5, 7, 2, 7, 5, 8, 3, 7, 4, 5, 1).
Thus, we have B = (1, 4, 3, 2, 3, 4, 1). We should report the 1-st through 7-th elements of this sequence.
Sample Input 2
1 1 4
2 5
Sample Output 2
4 3 2 3
Again, we have B = (1, 4, 3, 2, 3, 4, 1). We should report the 2-nd through 5-th elements of this sequence.
