Answer 2

import Foundation

func getLastWord(_ input: String) -> String {
    // Trim leading/trailing whitespace
    let trimmed = input.trimmingCharacters(in: .whitespacesAndNewlines)

    // If empty after trimming, return empty string
    guard !trimmed.isEmpty else { return "" }

    // Split on whitespace and return the last element
    return trimmed
        .split(whereSeparator: { $0.isWhitespace })
        .last
        .map(String.init) ?? ""
}

let tests = [
    "vb.net javascript php c c++ python swift",
    "",
    "c#",
    "c c++ java ",
    "  "
]

for (i, t) in tests.enumerated() {
    print("\(i + 1). \(getLastWord(t))")
}
