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 word1does not equal toword2, and word1 and word2 are both in the list.
这道题小心重复
public class Solution { public int shortestDistance(String[] words, String word1, String word2) { int w1 = -1; int w2 =-1; int min = Integer.MAX_VALUE; for(int i=0; i<words.length;i++){ if(words[i].equals(word1)){ w1 = i; } if(words[i].equals(word2)){ w2 = i; } if(w1 != -1 && w2 != -1){ if(Math.abs(w1-w2)<min){ min = Math.abs(w1-w2); } } } return min; } }
