DSA Helpers
Run common data structure and algorithm utilities - binary search, bubble sort, GCD/LCM, prime checks, Fibonacci, and more - against your own input. Runs entirely in your browser.

Result
How the DSA helpers work
- Pick a utility from the dropdown - a sample input fills in automatically.
- Adjust the input values to match what you're working with.
- Read the computed result, including step counts where relevant.
FAQ
Which algorithms and utilities are included?
Binary search, bubble sort, GCD/LCM, prime checking, a Fibonacci sequence generator, and an array-reversal utility that mimics reversing a singly linked list.
Can I use this to prep for coding interviews?
Yes - it is a quick way to sanity-check the output of a classic algorithm against a small input while you study or debug your own implementation.
How large an input can I use?
These are demonstration-scale utilities meant for small inputs (a handful to a few dozen values) rather than production-scale datasets.
Is my data uploaded anywhere?
No - every computation runs locally in your browser using plain JavaScript. Nothing is sent to a server.
