Two Strings Are Anagrams

 



Write a method anagram(s,t) to decide if two strings are anagrams or not.

 判断两个字符串里的字符是否相同,也就是是否能够通过改变字母顺序而变成相同的字符串。

如果是返回true,如果不是返回false。

 

Clarification

What is Anagram?
- Two strings are anagram if they can be the same after change the order of characters.

Example

Given s = "abcd", t = "dcab", return true.
Given s = "ab", t = "ab", return true.
Given s = "ab", t = "ac", return false.

 

 

public class Solution {    /**     * @param s: The first string     * @param b: The second string     * @return true or false     */    public boolean anagram(String s, String t) {        if (s.length() != t.length()) {            return false;        }        int[] count = new int[256];                for(int i = 0; i < s.length(); i++) {            count[(int) s.charAt(i)]++;        }                for(int j = 0; j < t.length(); j++) {            count[(int) t.charAt(j)]--;            if (count[(int) t.charAt(j)] < 0){                return false;            }        }        return true;    }};
