Problem Statement
You are given a sequence $A=(A_1,A_2,\ldots,A_N)$ of length $N$ and positive integers $P,Q,R$, and $S$.
Here, $P,Q,R$, and $S$ satisfy $1\leq P\leq Q<R\leq S \leq N$ and $Q-P=S-R$.
Let $B=(B_1, B_2,\ldots, B_N)$ be the sequence obtained by swapping the $P$-th through $Q$-th terms and the $R$-th through $S$-th terms of $A$.
Print the sequence $B$.
Constraints
- $1\leq N \leq 100$
- $1\leq A_i\leq 100$
- $1\leq P\leq Q<R\leq S \leq N$
- $Q-P=S-R$
- All values in the input are integers.
Input
The input is given from Standard Input in the following format:
Output
Print $B_1, B_2,\ldots, B_N$, with spaces in between.
8 1 3 5 7
1 2 3 4 5 6 7 8
5 6 7 4 1 2 3 8
Swapping the $1$-st through $3$-rd terms $(1,2,3)$ and the $5$-th through $7$-th terms $(5,6,7)$ of the sequence $A=(1,2,3,4,5,6,7,8)$ results in $B=(5,6,7,4,1,2,3,8)$, which should be printed with spaces in between.
5 2 3 4 5
2 2 1 1 1
2 1 1 2 1
The same integer may occur multiple times in the sequence.
