csharp基础练习题:奇数之和【难度:1级】:

给定连续奇数的三角形:

             1
          3 5
       7 9 11
   13 15 17 19
21 23 25 27 29
...

从行索引(从索引1开始)计算此三角形的行和,例如:

rowSumOddNumbers(1); // 1
rowSumOddNumbers(2); // 3 + 5 = 8

row_sum_odd_numbers(1);#1
row_sum_odd_numbers(2);#3 + 5 = 8

生锈
row_sum_odd_numbers(1);#1
row_sum_odd_numbers(2);#3 + 5 = 8

row_sum_odd_numbers(1);#1
row_sum_odd_numbers(2);#3 + 5 = 8

rowSumOddNumbers(1); // 1
rowSumOddNumbers(2); // 3 + 5 = 8

rowSumOddNumbers(1); // 1
rowSumOddNumbers(2); // 3 + 5 = 8

rowSumOddNumbers 1 // 1
rowSumOddNumbers 2 // 3 + 5 = 8

rowSumOddNumbers 1  -  1
rowSumOddNumbers 2  -  3 + 5 = 8

row_sum_odd_numbers(1)#1
[1] 1
row_sum_odd_numbers(2)#3 + 5
[1] 8

如果:NASM
row_sum_odd_numbers:

mov rdi 1
调用row_sum_odd_numbers; rax < -  1

mov rdi 2
调用row_sum_odd_numbers; rax < -  3 + 5

(行和奇数1)#1
(行和奇数2)#3 + 5 = 8

rowsumoddnumbers(1)#1
rowsumoddnumbers(2)#3 + 5 = 8

rowSumOddNumbers(1)// 1
rowSumOddNumbers(1)// 3 + 5 = 8

编程目标:

using System;
public static class Kata
{
  public static long rowSumOddNumbers(long n)
  {
    // TODO
  }
}

测试样例:

using System;
using NUnit.Framework;
[TestFixture]
public class Test
{
[Test]
  public void test1() 
  {
    Assert.AreEqual(1,Kata.rowSumOddNumbers(1));
  }
}
