Help with this coding problem.

Hello all, can someone diagnois what does it mean by this code stack?

public class Solution {
    public int[] SortArrayByParityII(int[] nums) {
       int n = Convert.ToInt32(nums);
        if(n % 2 == 0)
        {
            Console.WriteLine(n);
        }
        else
        {
            Console.WriteLine(n);
        }
    }
}

public class Solution {
    public int[] SortArrayByParityII(int[] nums) {
       int n = Convert.ToInt32(nums);
        if(n % 2 == 0)
        {
            Console.WriteLine(n);
        }
        else
        {
            Console.WriteLine(n);
        }
    }
}

The problem is

Line 2: Char 18: error CS0161: 'Solution.SortArrayByParityII(int[])': not all code paths return a value (in Solution.cs)

Line 2: Char 18: error CS0161: 'Solution.SortArrayByParityII(int[])': not all code paths return a value (in Solution.cs)

I've tried converting the array in the method to an int type but that doesn't work

The int[] in your method definition is you saying that the method will return an array of ints, but you're not doing that

Oh, thank you

public class Solution {
    public int[] SortArrayByParityII(int[] nums) {
       int n = Convert.ToInt32(nums);
        if(n % 2 == 0)
        {
            Console.WriteLine(n);
        }
        else
        {
            Console.WriteLine(n);
        }
        return int[] result = n.ToString().Select(o=> Convert.ToInt32(n)).ToArray();
    }
}

public class Solution {
    public int[] SortArrayByParityII(int[] nums) {
       int n = Convert.ToInt32(nums);
        if(n % 2 == 0)
        {
            Console.WriteLine(n);
        }
        else
        {
            Console.WriteLine(n);
        }
        return int[] result = n.ToString().Select(o=> Convert.ToInt32(n)).ToArray();
    }
}

it's still not converting even with the above code

Convert.ToInt32(nums) Is this line not giving you an error? Also not really sure what you're trying to do in your return statement, or why you're assigning to a new variable to instantly return it

The Convert.ToInt32 isn't giving me any errors, but I am attempting to have it where the numbers when divided by 2 come out as even, else they come out as odd. It requires that i have a return as an array though

SinFluxx•10mo ago

I don't think you mean to be passing the whole array into the convert method though, or why you'd need to convert to int when it's already an array of ints?

I am attempting to have it where the numbers when divided by 2 come out as even, else they come out as odd

I'm not sure what you mean here?

Angius•10mo ago

You will need to use a loop, then Loop over the items in nums Parse each to an int Then check if that int is even or odd

Thanks I thought I would have to cast the array as an integer first, then back return as an array
