swift
Parameters: array: [Int]
The input is an array of integers
Returns: [Int] - A sorted array in ascending order
This educational content focuses on a Swift function, 'sortArrayAscending', which sorts an array of integers in ascending order, returning a new array. Ideal for programmers learning to work with array sorting algorithms in Swift.
Greetings fellow programmer! In this blog post, we're going to delve into the world of Swift programming by dealing with array sorting. We will write a function called 'sort-array-asc' that sorts an array in ascending order. So stay with us, grab a cup of coffee, and let's start this exciting journey together. We have made sure to explain each step in a simple and understandable way. Enjoy the learning process!
Firstly, we have to define our function. We do this by writing func sortArrayAsc(array: [Int]) -> [Int] { } Here, func is used to declare a function in Swift, sortArrayAsc is the name of our function, (array: [Int]) -> [Int] means that our function takes in an array of integers as an argument and returns an array of integers which will be sorted in ascending order.
func sortArrayAsc(array: [Int]) -> [Int] { }
Swift has a built-in sort function that we can use to sort our array. Inside our sortArrayAsc function, we can simply return the result of calling the sort function on our array. The sort function will sort the elements of the array in ascending order by default.
func sortArrayAsc(array: [Int]) -> [Int] {
return array.sorted()
}
To ensure that our function works as expected, we can call the function with an unsorted array of integers and print the result.
let unsortedArray = [5, 3, 9, 1, 6]
let sortedArray = sortArrayAsc(array: unsortedArray)
print(sortedArray) // [1, 3, 5, 6, 9]
Final code:
func sortArrayAsc(array: [Int]) -> [Int] {
return array.sorted()
}
let unsortedArray = [5, 3, 9, 1, 6]
let sortedArray = sortArrayAsc(array: unsortedArray)
print(sortedArray) // [1, 3, 5, 6, 9]
In conclusion, we have created a function sortArrayAsc that takes an unsorted array of integers as an argument and returns a new array with the same integers sorted in ascending order. We have also verified that our function works as expected by testing it with a sample input.
The function relies on a simple mathematical principle known as comparison sorting. It iteratively compares pairs of elements, switching their positions if necessary, until the list is sorted. This is typically accomplished in Swift using the built-in 'sort' method.
