Reverse an Array
Question:
You will be given
n numbers. Reverse the elements in the positions
a through b.
Input specification
In the first line, you will be given three
numbers (n, a and b). Then, in the following
line, you will be given comma-separated n integers
which are between -10000 and 10000 where
n is between 1 and 10000 and 1 ≤ a ≤ b ≤ n.
Note: Assume that the number positions
are from 1 to n.
Output specification
After reversing the numbers in the positions a through b,
show all the numbers (show numbers by separating spaces).
