Aug 9, 2017 · Solution 1: As the time complexity needs to be linear, the array of integers could be traversed only for once. To remove every pair of same number, XOR is the best option here and it’s also...
Dec 6, 2012 · The problem: Given an array of integers, every element appears twice except for one. Find that single one. Java Solution 1. The key to solve this problem is bit manipulation. XOR will return 1 only on two different bits. So if two numbers are the same, XOR will return 0. Finally only one number left.
Aug 13, 2021 · 1. Using Brute Force. The most obvious solution is to start with a Brute Force approach. In this approach, you can compare each number with the rest of the numbers in the array. In case you find...
