How to print number, which missing between ranges?

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

for numbers in Range1.upperBound...Range2.lowerBound{
 
    print(numbers)
 
}

Am I understanding your question correctly?

You can try something like this:

let rangeA = 1...10 let rangeB = 14...22

let numsBetweenRanges = Set(rangeA).symmetricDifference(Set(rangeB)) let missingNums = Array(numsBetweenRanges).sorted().filter { num in !range1.contains(num) || !range2.contains(num) }

print(missingNums) // Output: [11, 12, 13]

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

@OShv

That did not work. It gives:[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 14, 15, 16, 17, 18, 19, 20, 21, 22]

I changed to:

let rangeA = 1...10
let rangeB = 14...22
let mini = min(rangeA.min()!, rangeB.min()!)
let maxi = max(rangeA.max()!, rangeB.max()!)
let allRange = mini...maxi
var missing : [Int] = Array(allRange).sorted().filter() {num in !rangeA.contains(num) && !rangeB.contains(num)}
print(missing)

And get the expected result.

 
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)      
      }

This is how I solved it, maybe not the most efficient way but....

import Foundation
 
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
 
print(" ")
if (Maxi1 > Mini){
      print ("No free numbers between Range1 to Range2")
      }
      else {
            print("Free numbers between Range1 to Range2: ",Maxi+1 ... Mini-1)      
      }
 
print(" ")
print("All missing numbers between Range1 to Range2:")
 
let mini = min(Range1.min()!, Range2.min()!)
let maxi = max(Range1.max()!, Range2.max()!)
let allRange = mini...maxi
var missing : [Int] = Array(allRange).sorted().filter() {num in !Range1.contains(num) && !Range2.contains(num)}
print(missing)

Should find the way how to use the loop?
