Introduction
In this question, every element appears an even number of times except for one element, which appears an odd number of times. The element that appears an odd number of times is our answer.
Let’s see how to achieve this using the XOR operator.
Problem statement
We need to write a program to find the element, which is repeated odd number of times.
Input: {4, 3, 3, 4, 4, 4, 5, 3, 5}
Output: 3
