[英]What is wrong with my code? There is some problem with printing correctly the numbers which sum of the digits end with the number 3 and the number 6
我想知道我所謂的致命錯誤在哪里,因為我是使用C#編碼的新手,但在這種情況下,我真的看不出有什么問題。
List<int> numbers = Console.ReadLine().Split(',').Select(int.Parse).ToList();
List<int> even = new List<int>();
List<int> odd = new List<int>();
List<int> sum3 = new List<int>();
List<int> sum6 = new List<int>();
int sum = 0;
foreach(var nums in numbers)
{
if(nums%2==0 && nums % 10 == 4 || nums % 10 == 2)
{
even.Add(nums);
}
else if(nums % 2 != 0 && nums % 10 == 5 || nums % 10 == 7)
{
odd.Add(nums);
}
int n = nums;
while (n != 0)
{
sum += n % 10;
n = n / 10;
}
if (sum % 10 == 3)
{
sum3.Add(nums);
}
else if (sum % 10 == 6)
{
sum6.Add(nums);
}
}
Console.WriteLine(String.Join(',',even));
Console.WriteLine(String.Join(',', odd));
Console.WriteLine(String.Join(',', sum3));
Console.WriteLine(String.Join(',', sum6));
您忘記為每個數字更改變量sum = 0
。
只需更新foreach
循環中每個步驟的變量總和。
請查看下一個代碼:
int sum = 0;
foreach(var nums in numbers)
{
if(nums%2==0 && nums % 10 == 4 || nums % 10 == 2)
{
even.Add(nums);
}
else if(nums % 2 != 0 && nums % 10 == 5 || nums % 10 == 7)
{
odd.Add(nums);
}
sum = 0; // There is your issue (you forget about it)
int n = nums;
while (n != 0)
{
sum += n % 10;
n = n / 10;
}
if (sum % 10 == 3)
{
sum3.Add(nums);
}
else if (sum % 10 == 6)
{
sum6.Add(nums);
}
}
