swift
Parameters: firstArray: [Int], secondArray: [Int]
Two arrays of integers to compare
Returns: An array of integers
This function takes two arrays as input and returns an array that contains the difference between the two. The difference is computed by excluding common elements in both arrays.
Hello, Programmer. Today's blog post walks you through a simple yet, intriguing task - programming a function to find the difference between two arrays in Swift. You'll get a thorough step-by-step guide on implementing this function. Happy coding!
The function uses the concept of Set Differences in mathematics, which is a part of Set Theory. In a Set A and B, the difference (A-B) is the set of elements which are only in A but not in B. Similarly, the difference (B-A) is the elements in B but not in A. For example, if `A = {1,2,3}` and `B = {2,3,4}`, the difference A-B = `{1}`, and the difference B-A = `{4}`.
