Solution: Shortest Word Distance II

Explore how to implement the WordDistance class that stores word positions to quickly find the shortest distance between any two words in an array. Understand the use of dictionary indexing and two-pointer traversal to optimize query time while managing space complexity effectively.

Statement

Design a data structure that takes in an array of strings and efficiently computes the shortest distance between any two different strings in the array.

Implement the WordDistance class:

  • WordDistance(String[] wordsDict): Initializes the object with an array of strings.

  • int shortest(String word1, String word2): Returns the shortest distance between word1 and word2 in the array of strings.

Constraints:

  • 11 \leq wordsDict.length 103\leq10^3

  • 11 \leq wordsDict[i].length ...
