Given two strings s
and t
, return true
if t
is an anagram of s
, and false
otherwise.
An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once.
Example 1:
Input: s = "anagram", t = "nagaram"
Output: true
Example 2:
Input: s = "rat", t = "car"
Output: false
Constraints:
1 <= s.length, t.length <= 5 * 104
s
and t
consist of lowercase English letters.public class Solution {
public boolean isAnagram(String s, String t) {
int[] alphabet = new int[26];
for (int i = 0; i < s.length(); i++) alphabet[s.charAt(i) - 'a']++;
for (int i = 0; i < t.length(); i++) alphabet[t.charAt(i) - 'a']--;
for (int i : alphabet) if (i != 0) return false;
return true;
}
}
class Solution {
public:
bool isAnagram(string s, string t) {
sort(s.begin(), s.end());
sort(t.begin(), t.end());
return s == t;
}
};
class Solution:
def isAnagram(self, s, t):
return Counter(s) == Counter(t)
