For a given N, prints the sum of even and odd integers of the first N natural numbers.

Example 1:

Input:
N = 1
Output:
0 1
Explanation:
Natural numbers less than 1 are only 1.
So the sum of even number = 0.
and the sum of odd number = 1.

Example 2:

Input:
N = 6
Output:
12 9
Explanation:
Natural numbers less than 6 are
1 2 3 4 5 6
So the sum of even number = 2 + 4 + 6 = 12.
and the sum of odd number = 1 + 3 + 5 = 9.

Your Task:
You don't need to read input or print anything. Your task is to complete the function getSum() which takes an integer N as input parameter and return the sum of even and odd natural number less than equal to N.

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

Constraints:
1<= N <=104
