Are you ready to ace your technical interviews? 🚀 Dive into the world of the infamous Single Number Question with us in this comprehensive guide! 🎓

Using Sorting
To improve on the brute force approach you can apply sorting first to avoid going back and forth in the array while comparing each number with the rest of the numbers in the array. After sorting you would just need a single pass on the array of numbers to find a single number. Sorting can be done in O(N logN) time, this approach is faster than the above one. Also, we don’t need additional space so the space complexity would be O(1). Please find the Java code of the solution for this approach below.

In this video, we'll break down the strategies and approaches needed to tackle one of the most common and challenging questions asked by tech companies in their technical rounds. From Google to Facebook, this question is a staple in interviews, testing not only your problem-solving skills but also your ability to think critically and efficiently.
