In this assignment, you write a C++ program that outputs each number and its rank in the list from a given list of 20 distinct integers. The rank of a number x in list L is the number of elements smaller than x in L.

For example,

Input: 20 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 1
Output: (20 19) (2 1) (3 2) (4 3) (5 4) (6 5) (7 6) (8 7) (9 8) (10 9) (11 10) (12 11) (13 12) (14 13) (15 14) (16 15) (17 16) (18 17) (19 18) (1 0)
/* the order of the pairs in the list in the output is not important */

Your program must implement the following algorithm:

Read input of N=20 integers into array A

Scan array A as index i runs from 0 to N-1

calculate the rank of A[i] by counting all numbers that are smaller than A[i]

Output all elements and their ranks in list L (i.e. array A)

In this assignment you are asked to implement list L as an array of size N such that each element in L is a structure that contains an element and its rank in array A.
