Array DS Hackerrank Challenge

An array is a type of data structure that stores elements of the same type in a contiguous block of memory. In an array, (A) of size (N), each memory location has some unique index, (i) (where (0 \leq i < N)), that can be referenced as (A[i]) or (A_i).

Reverse an array of integers.

Example

Given:

[A = [1, 2, 3]]

Return:

[ [3, 2, 1] ]

Function Description

• The second line contains (N) space-separated integers that make up (A).

Constraints

• (1 \leq N \leq 10^3)
• (1 \leq A[i] \leq 10^4), where (A[i]) is the (i^{th}) integer in (A)
