// Problem: Employees-Friends-Divisions Association Mapping

// Input 1. employeesInput: 3 comma separated data fields:  id, name, division
// Input 2. friendsInput: 2 comma separated data fields: ids of 2 employees who are friends
//
// Task 1: Associate each employee with his list of friends
// Task 2: Count the following:
//         1. The number of employees in each division
//         2. The number of employees per division who have friends outside of his division

// Problem: Find the rectangles inside the input image array

// Input: An array representing an image, where 1 represents pixel on, 0 off

// Task 1:  Find the rectangle (top-left coordinate, width, height) in an array containing a single rectangle
// Task 2:  Find all the rectangles inside an array containing multiple rectangles

// image1 expected result:  top-left = (2,3), width = 4, height = 3
