- Shortest Word Distance
Shortest Word Distance
Given a list of words and two words word1 and word2, return the shortest distance between these two words in the list.
For example,
Assume that words = ["practice", "makes", "perfect", "coding", "makes"].
Given word1 = "coding", word2 = "practice", return 3.
Given word1 = "makes", word2 = "coding", return 1.
Note:
You may assume that word1 does not equal to word2, and word1 and word2 are both in the list.
Solution:
1. public class Solution {
2. public int shortestDistance(String[] words, String word1, String word2) {
3. int p1 = -1, p2 = -1, min = words.length;
4. boolean updated = false;
5. 6. for (int i = 0; i < words.length; i++) {
7. if (word1.equals(words[i])) {
8. p1 = i;
9. updated = true;
10. }
11. 12. if (word2.equals(words[i])) {
13. p2 = i;
14. updated = true;
15. }
16. 17. if (p1 != -1 && p2 != -1 && updated) {
18. updated = false;
19. min = Math.min(min, Math.abs(p1 - p2));
20. }
21. }
22. 23. return min;
24. }
25. }
