Q3. Let's add the year of the album to the 'albumMutable' variable. Where the key is a NSString 'year' and the value is also a NSString '1969'.
<p>NSDictionary *album = @ {@"title" : @"Abbey Road", @"artist": @"The Beatles"}; </p> <p>NSMutableDictionary *albumMutable = [NSMutableDictionary dictionaryWithDictionary:album];</p> <p>[albumMutable setObject:@1969 forKey:@"year"];</p>
