在棋s中计算具有奇数边长的正方形

给定N * N的棋盘，任务是计算边长为奇数的方格数。

例子：

Input: N = 3
Output: 10
9 squares are possible whose sides are 1
and a single square with side = 3
9 + 1 = 10

Input: N = 8
Output: 120

方法：对于从1到N的所有奇数，然后计算可以形成具有该奇数边的平方数。对于^第i^个面，正方形的计数等于(N – I + ^1)2。进一步加上所有这样的平方数。

下面是上述方法的实现：

C++

// C++ implementation of the approach
#include 
using namespace std;
  
// Function to return the count
// of odd length squares possible
int count_square(int n)
{
  
    // To store the required count
    int count = 0;
  
    // For all odd values of i
    for (int i = 1; i <= n; i = i + 2) {
  
        // Add the count of possible
        // squares of length i
        int k = n - i + 1;
        count += (k * k);
    }
  
    // Return the required count
    return count;
}
  
// Driver code
int main()
{
    int N = 8;
  
    cout << count_square(N);
  
    return 0;
}

Java

// Java implementation of the approach
class GFG {
  
    // Function to return the count
    // of odd length squares possible
    static int count_square(int n)
    {
  
        // To store the required count
        int count = 0;
  
        // For all odd values of i
        for (int i = 1; i <= n; i = i + 2) {
  
            // Add the count of possible
            // squares of length i
            int k = n - i + 1;
            count += (k * k);
        }
  
        // Return the required count
        return count;
    }
  
    // Driver code
    public static void main(String[] args)
    {
        int N = 8;
  
        System.out.println(count_square(N));
    }
}

    for i in range(1, n + 1, 2):
  
        # Add the count of possible
        # squares of length i
        k = n - i + 1;
        count += (k * k);
  
    # Return the required count
