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 $B_L, \ldots, B_R$.
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 $B$.
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.
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.
