Future training-OddOccurrencesInArray

Here is another codility problem solution from the codility lessons (OddOccurrencesInArray - Find value that occurs in odd number of elements.) due to the copy rights I can't copy the content of the problem here so to view the problem description click here.

// you can also use imports, for example:
// import java.util.*;

// you can use System.out.println for debugging purposes, e.g.
// System.out.println("this is a debug message");
// XORing any 2 similar number will give us zero 
//Zoring Zero with any number will give us the number
class Solution {
 public int solution(int[] A) {
  // write your code in Java SE 8
  int unPairedNum = A[0];
  for (int i = 1; i < A.length; i++) {
   unPairedNum = unPairedNum ^ A[i];
  }
  return unPairedNum;
 }
}
