title: Merge two arrays and omit all repeating elements
body: <p>I have 2 arrays. Input 1 and Input 2. Suppose input 1 has {1,1,2,3,3,4,5} and input 2 has {4,2,6,7,8}.  Merged array {1,1,2,3,3,4,5,4,2,6,7,8}</p>
  
  <p>After sorting my merged array looks like {1,1,2,2,3,3,4,4,5,6,7,8} </p>
  
  <p>My output should be like {5,6,7,8} because those are non-repeating elements. It should have neither occurred twice in 1st nor once in 1st and once in 2nd. </p>
  
  <p>I have put both the arrays into one single array(merged both). Sorted it and removed duplicates also.  I am getting the output like {1,2,3,4,5,6,7,8} but i should not get 1,2,3,4 as they all have occurred twice in the merged array.</p>
  
  <p>Please help me to finish the program soon. Thanks in advance.</p>
  
  <p>I cant use structures. Thats my task.</p>
