Problem Statement
What is a trie data structure?
Step-by-Step Explanation
A trie stores strings by sharing prefixes across linked nodes.
- Identify what the question is asking. In Data Structures, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
- Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
- Work one step at a time and keep units, signs, and restrictions visible.
- Check whether the answer makes sense in the original context.
Final Answer
A trie stores strings by sharing prefixes across linked nodes. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
