242. valid anagram java_Leetcode242 Valid Anagram JAVA语言
Given two strings s and t, write a function to determine if t is an anagram of s.
For example,
s = "anagram", t = "nagaram", return true.
s = "rat", t = "car", return false.
题意：给的两个字符串判断是否是相同字符组成的不同字符串public class Solution {
public boolean isAnagram(String s, String t) {
int[] ret=new int[26];
for(int i=0;i
ret[s.charAt(i)-'a']--;
}
for(int i=0;i
++ret[t.charAt(i)-'a'];
}
for(int i=0;i<26;i++){
if(ret[i]!=0)
return false;
}
return true;
}
}
PS：参见之前的那个勒索信的那个，直接hash求出每个字符的数量即可
