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

**Example 1:**

Input:N = 1Output:0 1Explanation: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 = 6Output:12 9Explanation: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 <=10^{4}
