The Union method

The Union method on the Set class returns a unionSet that consists of a union of set and anotherSet. Both sets are traversed through integerMap keys, and union set is updated with elements from the sets, as follows:

//Union method returns the set which is union of the set with anotherSet

func (set *Set) Union(anotherSet *Set) *Set{
 var unionSet = & Set{}
 unionSet.New()
 var value int
 for(value,_ = range set.integerMap){
   unionSet.AddElement(value)
 }
 
 for(value,_ = range anotherSet.integerMap){
   unionSet.AddElement(value)
 }
 
 return unionSet 
}

The example output after invoking the union method with the anotherSet parameter is as follows. A new unionSet is created. The current set and another set values are iterated. Every value is added to the union set:

Let's take a look at the main method in the next section.
