Questions & Step-by-Step Solutions
Which of the following statements about Disjoint Set Union is true?
Step 1: Understand what Disjoint Set Union (DSU) is. It is a data structure that keeps track of a partition of a set into disjoint (non-overlapping) subsets.
Step 2: Learn that DSU can efficiently answer questions about whether two elements are in the same subset (connected) or not.
Step 3: Recognize that DSU supports two main operations: 'find' (to determine the subset a particular element belongs to) and 'union' (to merge two subsets).
Step 4: Note that DSU is particularly useful in scenarios where the connectivity between elements changes over time, such as in network connectivity problems.
Step 5: Conclude that the statement about DSU efficiently handling dynamic connectivity queries is true, as it is designed for such tasks.
