Valid Anagram

Medium

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

[
  "anagram",
  "nagaram"
]

Output

true

Explanation. nagaram is formed by rearranging the letters of anagram.

Example 2

Input

[
  "rat",
  "car"
]

Output

false

Explanation. rat and car do not contain the same characters in the same counts.

Example 3

Input

[
  "listen",
  "silentt"
]

Output

false

Explanation. The strings have different lengths, so they cannot be anagrams.

Example 4

Input

[
  "a",
  "a"
]

Output

true

Explanation. A single character string is an anagram of itself.

Example 5

Input

[
  "aabbc",
  "abcab"
]

Output

true

Explanation. Both strings have two 'a's, two 'b's, and one 'c'.

Example 6

Input

[
  "aabb",
  "bbaa"
]

Output

true

Explanation. aabb is an anagram of bbaa, as both contain two 'a's and two 'b's.

Example 7

Input

[
  "ab",
  "ba"
]

Output

true

Explanation. ab is an anagram of ba.

Example 8

Input

[
  "abacaba",
  "aabbaac"
]

Output

false

Explanation. Counts of characters don't match: 'b' count is 2 in s, 2 in t. 'c' count is 1 in s, 1 in t. 'a' count is 4 in s, 4 in t. This is true. Let's make it more distinct. s: 'abacaba', t: 'aababca'. s = {a:4, b:2, c:1}. t = {a:4, b:2, c:1}. This is true. Let's make it different. s="aabbc", t="abbcc"

Example 9

Input

[
  "aabbc",
  "abbcc"
]

Output

false

Explanation. String s has two 'a's, two 'b's, and one 'c'. String t has one 'a', two 'b's, and two 'c's. The character counts do not match.

Follow-up: What if the input strings contain Unicode characters? How would you adapt your solution?

Constraints:

1 <= s.length, t.length <= 5 * 10^4.s and t consist of lowercase English letters.
