Problem
Given an array of
N elements (
\(2<=N<=15\)). Rearrange elements from number
a to number
b in reverse order.
Input
At the input, in the first line
N is a number, in the second line there are two integers
a and
b (
\(a<b\)) - indexes of the elements in the range of which it is necessary to rearrange the array elements. The third line contains
N numbers - the values of the array elements.
Array element numbering starts from
1.
