Given a positive integer **N**, count the number of possible ways to represent **N** as the sum of four positive integers.

**Example 1:**

**Input:**
N = 5
**Output:**
1
**Explanation:**
We can represent 5 as
a sum of 4 positive integers,
only in 1 way as 1+1+1+2 = 5

**Example 2:**

**Input:**
N = 41
**Output:**
511
**Explanation:**
We can represent 41 as
sum of 4 positive integers
in 511 ways

**Your Task:**

You don't need to read input or print anything. Your task is to complete the function **countWays()** which takes an integer **N** as input parameter and returns an integer, the total count of the number of ways N can be represented as sum of 4 positive numbers.

**Expected Time Complexity:** O(N^{4})

**Expected Space Complexity:** O(1)

**Constraints:**

0 <= N <= 100
