Store days

arrays.cpp

/**
 Opening and closing hours for a store:
 Given two arrays of si*ze seven that respectively indicate opening and closing hours over days of week for a store, print the store hours in friendly format.
 Special Conditions:
 1. If opening hours are greater than closing hours, the store is assumed closed on that day.
 2. If opening/closing hours are greater than 2400 hours or for any other error condition, the store is assumed closed that day.
 3. If opening hours are equal to closing hours, the store is open for 24 hours.
 
 Example:
 Open - [900,1000,1000,1000,2700,1200,800]
 Close - [1700,1600,1600,1600,1600,1200,800]
 
 // 900 1000 1000 1000 2700 1200 800 -1
 // 1700 1600 1600 1600 1600 1200 800 -1
 
 Output:
 Mon: 900-1700
 Tue-Thur: 1000-1600
 Fri: Closed
 Sat-Sun: Open 24 Hours
