Question

我在将此作业问题转换为伪代码时遇到了一些麻烦。我想知道逻辑是否正确。

问题：

编写一个打印以下元素的程序：1,3,5,7,9,11,13,15,17,19，直到用户输入的值。该程序每行不应打印超过10个数字。打印的最后一行可能小于10.除了第一个数字和最后一个数字之外，应该有一个“，”分隔所有数字。每行上的最后一个数字后面应该有一个“。”。在退出之前，它还应打印所有元素的总和：计算项目的总和并输入结果。例如，如果用户输入76，则输出应如下所示   程序的示例运行应如下：

输入您的号码（＆gt; = 1和＆lt; = 100）：76   你的序列是

1,3,5,7,9,11,13,15,17,19。   21,23,25,27,29,31,33,35,37,39。   41,43,45,47,49,51,53,55,57,59。   61,63,65,67,69,71,73,75。

上述元素的总和1444。

您提出的算法使用可以保存的内存，因为我们需要打印所有奇数整数，可以使用四个变量解决问题，一个用于跟踪总和，一个用于更改行，一个用于用户输入和一个作为循环变量。

Variables:

sum   :int   // keeps track of the sum
count :int   // keeps track of the Integer printed in a line.
i     :int   // looping variable.
n     :int   // Given as input
Algorithm:

/* BEGIN ALGORITHM */
n=input();
count=0;
sum=0
for(i=1:i<n:i=i+2){
                  print("i,");
                  count=count+1;
                  if(count>9){ 
                               print("/n"); // change line;
                               count=0;
                               }
                   sum=sum+i;
                   }
print("n."); 
print("Sum is (sum+n)");
/* END ALGORITHM */

这个伪代码的逻辑是否正确？
