Two numbers with odd occurrences
Easy Accuracy: 44.5% Submissions: 425 Points: 2

Given an unsorted array, arr[] of size N and that contains even number of occurrences for all numbers except two numbers. Find the two numbers in decreasing order which has odd occurrences.

Example 1:

Input:
N = 8
Arr = {4, 2, 4, 5, 2, 3, 3, 1}
Output: {5, 1}
Explaination: 5 and 1 have odd occurrences.

Example 2:

Input:
N = 6
Arr = {1 7 5 5 4 4}
Output: {7, 1}
Explaination: 7 and 1 have odd occurrences.

You don't need to read input or print anything. Your task is to complete the function twoOddNum() which takes the array Arr[] and its size as input parameters and returns the two numbers in decreasing order which have odd occurrences.

Expected Time Complexity: O(N)
Expected Auxiliary Space: O(1)

Constraints:
1 ≤ N ≤ 105
1 ≤ Arri ≤ 105
