Problem:
Reverse

Write a program which reads a sequence of integers $A = \{a_0, a_1, ..., a_{n-1}\}$ and reverse specified elements by a list of the following operation:

reverse($b, e$): reverse the order of $a_b, a_{b+1}, ..., a_{e-1}$

Input

The input is given in the following format.

$n$
$a_0 \; a_1 \; ...,\; a_{n-1}$
$q$
$b_1 \; e_1$
$b_2 \; e_2$
:
$b_{q} \; b_{q}$

In the first line, $n$ (the number of elements in $A$) is given. In the second line, $a_i$ (each element in $A$) are given. In the third line, the number of queries $q$ is given and each query is given by two integers $b_i \; e_i$ in the following $q$ lines.

Output

Print all elements of $A$ in a line after performing the given operations. Put a single space character between adjacency elements and a newline at the end of the last element.

Constraints

$1 \leq n \leq 1,000$

$-1,000,000,000 \leq a_i \leq 1,000,000,000$

$1 \leq q \leq 1,000$

$0 \leq b < e \leq n$

Sample Input 1

8
1 2 3 4 5 6 7 8
2
1 6
3 8

Sample Output 1

1 6 5 8 7 2 3 4

Solution in Python3 (judge verdict: Accepted)

n = int(input())
num = list(map(int, input().split()))

q = int(input())
for _ in range(q):
    start, end = map(int, input().split())
    tmp = num[start:end]
    tmp = tmp[::-1]
    num[start:end] = tmp

print(' '.join(str(n) for n in num))
