Detect anagram in string
Last updated: December 12, 2025
Quick Overview
Given two strings, determine if one string is an anagram of the other. An anagram is a rearrangement of the letters of one word to form another word, using all the original letters exactly once. The function should return true if the strings are anagrams and false otherwise, ignoring spaces and case sensitivity.

Coding interviews at Splunk focus on problem-solving approach as much as the final solution. The interviewer wants to see you break down the problem, consider edge cases, and optimize iteratively. Communication throughout the process is key.
What the Interviewer Expects
- Identify the correct data structure and algorithm for the problem
- Write clean, bug-free code with proper variable naming
- Analyze time and space complexity correctly
- Handle basic edge cases (empty input, single element)
- Communicate your thought process while coding
Key Topics to Cover
How to Approach This
- Clarify input constraints and edge cases before writing code.
- Walk through your approach verbally and confirm with the interviewer before coding.
- Start with a brute force solution, then optimize. Mention time and space complexity.
- Test your solution with examples, including edge cases like empty input or duplicates.
- Consider common patterns: sliding window, two pointers, hash map, BFS/DFS, dynamic programming.
Possible Follow-up Questions
- Can you solve this iteratively instead of recursively (or vice versa)?
- What if the input doesn't fit in memory?
- What happens if the input contains duplicates?
- What is the worst-case input for your solution?

Problem Analysis
To determine if one string is an anagram of another, we can utilize the frequency counting pattern. This approach involves counting the occurrences of each character in both strings and comparing ...
Approach
- Normalize the strings: Convert both strings to the same case (e.g., lowercase) and remove any spaces. For example, for the input strings 'Listen' and 'Silent', we would transform them to 'liste...
