OC 和 swift 冒泡排序

?

1 2 3 4 5 6 7 8 9 10 11 12 13

swift 版           var numbers = [17, 28, 36, 15, 39]         print("排序前\(numbers)")                   for i in 0..<numbers.count - 1 {             for j in 0..<numbers.count - 1 - i {                 if numbers[j] > numbers[j + 1] {                     numbers.swapAt(j, j+1)                 }             }         }         print("排序后\(numbers)")
