Function to find index of non-duplicate member:

 int  findNonDuplicate(int A[],int n)
     int i;
     if(A[0]!=A[1] && A[1]==A[2])
          return 0;
    else {
               return (i+1);

But for this first we need to sort the array
sir,let me know if i understood you in a wrong way, i took example of 122222 and 221222 in both cases  2 is duplicate and 1 is not. First integer array satisfies first 'if' condition therefore it will return 0, while second array of integer returns 2. first if condition in my program is for special case in which non-duplicate number appears at 0'th index for rest else condition follows.
say if array is in the form of 1, 3, 4, 6, 8, 1, 3, 4, 6. Then answer would be 8 which is only non-duplicate member. Looks the function will not work on this.
i understood the question wrong thanks sir, i will correct my code asap.

Say you are given two arrays where second array is duplicate with one missing element. What should be the best possible way to find that missing element -
array1: [1,2,3,4,5,6,7]
array2: [1,3,4,5,6,7]

Missing Element: 2
