import Foundation print("Xcode Swift") // create some ranges let range1 = 1 ... 10 let range2 = 2 ... 10 let range3 = 3 ... 10 let range4 = 4 ... 10 let range5 = 5 ... 10 // Count the ranges together from range2 to range4 let range6 = range2.count + range3.count + range4.count // print the number of values print(range6)

I would like calculate range2 - range4 and I would like only specifyi start and end. (range2+range3+range4) import Foundation print("Xcode Swift") // create some ranges let range1 = 1 ... 10 let range2 = 2 ... 10 let range3 = 3 ... 10 let range4 = 4 ... 10 let range5 = 5 ... 10 // Count the ranges together from range2 to range4 let range6 = range2.count + range3.count + range4.count // print the number of values print(range6)

import Foundation print("Xcode Swift") // create some ranges let range1 = 1 ... 10 let range2 = 2 ... 10 let range3 = 3 ... 10 let range4 = 4 ... 10 let range5 = 5 ... 10 // Count the ranges together from range2 to range4 let range6 = range2.count + range3.count + range4.count // print the number of values print(range6)

// create some ranges let Range1 = 1 ... 10 let Range2 = 2 ... 10 let Range3 = 15 ... 20 let Range4 = 40 ... 44 let Range5 = 50 ... 60 // Count the ranges together from range2 to range4 let RangeBetween = Range2.count + Range3.count + Range4.count // print the number of values print(RangeBetween) Thanks, good point, but still I have not been able to solve this. I was also wondering how to get the missing numbers between the sets listed, example 11, 12, 13, 14..

Example, how to find number 11-13 and 23-25?

Example how to find following numbers: 11-13, 23-25 and 31-39?

print("Xcode Swift: Numbers") // create some ranges print (" ") let Range1 = 1 ... 10 let Range2 = 14 ... 22 let Range3 = 26 ... 30 let Range4 = 40 ... 44 let Range5 = 50 ... 60 print("Range1 SUM:",Range1.count) print("Range2 SUM:",Range2.count) print("Range3 SUM:",Range3.count) print("Range4 SUM:",Range4.count) print("Range5 SUM:",Range5.count) let Maxi = Range1.max()! let Mini = Range2.min()! let Maxi1 = Maxi+2 if (Maxi1 > Mini){ print ("No free numbers between Range1 to Range2") } else { print("Free numbers between Range1 to Range2: ",Maxi+1 ... Mini-1) } //Give answer: Xcode Swift: Numbers Range1 SUM: 10 Range2 SUM: 9 Range3 SUM: 5 Range4 SUM: 5 Range5 SUM: 11 Free numbers between Range1 to Range2: 11...13 [Done] exited with code=0 in 0.163 seconds This is how I solved it, maybe not the most efficient way but....
