Questions & Step-by-Step Solutions

In a Disjoint Set Union, what does the 'Union' operation do?
  • Step 1: Understand that a Disjoint Set Union (DSU) is a data structure that keeps track of a collection of disjoint (non-overlapping) sets.
  • Step 2: The 'Union' operation is used when you want to combine two separate sets into a single set.
  • Step 3: Identify the two sets you want to combine. For example, Set A and Set B.
  • Step 4: After performing the 'Union' operation, all elements from Set A and Set B will now belong to one new set.
  • Step 5: This means that any element that was in Set A or Set B can now be found in the combined set.
