Solution for hackerRank problem Arrays-DS in Python Problem : 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 <= i < N), that can be referenced as A[i] or Ai. Reverse an array of integers. Note: If you've already solved our C++ domain's Arrays Introduction challenge, you may want to skip this. Example A = [1, 2, 3] Return [3, 2, 1]. Function Description Complete the function reverseArray in the editor below. reverseArray has the following parameter(s): int A[n]: the array to reverse Returns int[n]: the reversed array Input Format The first line contains an integer, N, the number of integers in A. The second line contains N space-separated integers that make up A. Constraints 1 <= N <= 10^3 1 <= A[i] <= 10^4, where A[i] is the ith integer in A Sample Input 1 Sample Output 1 2 3 4 1 Code : #!/bin/python3 import math impor...
