What is the optimal time complexity of solving Valid Anagram?

The optimized solution achieves a time complexity of O(n) by using sorting, mathematical shortcuts, or hash table lookups.

What is the auxiliary space complexity for Valid Anagram?

The space complexity is O(n) since we only use a minimal/constant amount of extra memory for tracking variables (or auxiliary space if dynamic structures are allocated).

What are the typical edge cases we must handle in Valid Anagram?

Key edge cases include empty collections, negative or large bounds causing integer overflow, arrays with only one element, or inputs where target criteria are not met.

How can we optimize the brute force approach for Valid Anagram?

Brute force methods often inspect all possible combinations. We optimize this by sorting the input list to enable binary search, or tracking processed items in a set to avoid redundant nested loop lookups.

Valid Anagram

Learn how to solve the 'Valid Anagram' problem. This detailed resource details brute force and optimized approaches.

Mode Selected

Problem Statement

Easy

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.

Constraints

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

Examples

Example 1

Input

s = 'anagram', t = 'nagaram'

Output

true

Example 2

Input

s = 'rat', t = 'car'

Output

false

Need a Hint?

Analyze the input constraints. Try sorting first (O(n log n)) or using a hash map/set to track seen elements in O(n) time.

Edge Cases to Watch

Empty list or null input variables
Single item lists/arrays
Extremely large input bounds causing integer or stack overflow
