这个伪代码的逻辑是否正确？

Question

我在将这个作业问题转换为伪代码时遇到了一些麻烦。我想知道这个逻辑是否正确。

问题：

编写一个程序，打印如下内容：1，3，5，7，9，11，13，15，17，19，在这之前用户输入的值。该程序不应该打印每行超过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“，”将所有数字分开。每行上的最后一个数字后面应该有一个“。”。在退出之前，还应打印所有元素的总和：计算项目总数并输入结果。例如，如果用户输入76的输出应该如下 程序应尽可能的样品运行如下：

输入数（> = 1和< = 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。

由您提出的算法使用了可以保存下来，因为我们需要打印的所有奇数的问题，可以用四个变量，一个用于跟踪总和来解决内存，一个用于改变行，一个用于用户输入，另一个用作循环变量。

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 */
