About the challenge Level Points

Question

I passed it with this...

static void Main(string[] args)
{
int levels = Convert.ToInt32(Console.ReadLine());

Console.WriteLine(Points(levels));
}

static int Points(int levels)
{
//your code goes here
int total = (levels + 1) * levels / 2;
return total;
}

i was wondering if there was a way to use for or foreach method, i had try but cant figure it our. thanks if reply.

Answer 1

In description you have Total: 1+2+3 = 6 points where 1, 2 and 3 are levels. Therfore easier way is to use a for loop:

int total = 0
for (int i = levels; i > 0; i--){
total += i;
}
return total;

A foreach loop has no sense because for it will be needed an array. In such as loop will be accessed the array elements directly.

Answer 2

JaScript wow thanks! I tried the same code as you! Just dont know why i cant run it well at the first time...... must missing something i guess. Happy to know having the right concept.

and you are right about the foreach way, totally unnessary.

Answer 3

Congratulation and happy coding furthermore.

Answer 4

using System;
using System.Collections.Generic;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
int levels = Convert.ToInt32(Console.ReadLine());

Console.WriteLine(Points(levels));
}

static int Points(int levels)
{
//your code goes here
if(levels==0){
return 0;
}else{
return levels + Points(levels-1);
}

}

}

}

hooooraaaaaaa!!!!!!
