Question

Write a program to find the sum of all odd numbers recursively less than or equal to n starting from 1, where n is any positive number. So for example n is 11 find sum of the following numbers (1,3,5,7,9,11)

Write this in java please

Answer 1

public class SumOdd {

    public static int oddSum(int n) {
        if (n <= 0) {
            return 0;
        } else {
            int total = oddSum(n - 1);
            if (n % 2 == 1)
                total += n;
            return total;
        }
    }

    public static void main(String[] args) {
        System.out.println(oddSum(11));
    }
}
