Lexicographical Phrase Reconstructor Solution
Problem Statement
Given a collection of disjoint phrases, arrange them lexicographically to form the lexicographically smallest possible string.
Examples
Example 1:
Input:{"phrases":["apple","banana","cherry"]}
Output:applebananacherry
Example 2:
Input:{"phrases":["dog","cat","bird"]}
Output:birdcatdog
Constraints
- Each phrase is at most 50 characters long.
- The total number of phrases does not exceed 200.
Time: O(n log n) Space: O(n)
The optimal approach is to use a sorting algorithm to sort the phrases lexicographically, and then concatenate them in the sorted order. This approach has a time complexity of O(n log n) due to the sorting step.
