How to get intersection of two strings in Swift

Answer 1

let string1 = "php"
let string2 = "python"

// Convert strings to sets of characters
let set1 = Set(string1)
let set2 = Set(string2)

// Find the intersection
let intersection = set1.intersection(set2)

// Convert the result back to a string (if needed)
let intersectionString = String(intersection)

print("intersection (Common characters): \(intersectionString)")



/*
run:
   
intersection (Common characters): ph

*/
