import SwiftUI

struct ContentView: View {
    @State private var value: String = "Hello, World!"
    
    var body: some View {
        VStack {
            Text(value)
                .font(.largeTitle)
            
            Button(action: {
                value = "New Value"
            }) {
                Text("Change Value")
                    .font(.title)
                    .padding()
                    .background(Color.blue)
                    .foregroundColor(.white)
                    .cornerRadius(10)
            }
            
            NavigationLink(destination: DetailView(value: $value)) {
                Text("Go to Detail View")
                    .font(.title)
