Question

我正在尝试运行代码作为codechef的解决方案来解决这个问题：** https://www.codechef.com/problems/SIMDISH

虽然它正在编译并在我的cmd上提供正确的输出，但它在Codechef的提交上显示运行时错误。我搜索了这个问题，发现我的代码没有任何问题。在我无法使用的问题中存在一个约束：1≤T≤200，其中T是我的代码中的变量'pairs'

 public class SimpleController : Controller
    {
        public class FileViewModel
        {
            public byte[] Content { get; set; }

            public string FileName { get; set; }
        }

       [HttpPost]
       [ValidateInput(false)]
       public FileStreamResult covertopdf(string Htmlcontent)
        //public FileStreamResult covertopdf(file fo)
        {

            if (header == null && footer == null)
                doc.Rect.Inset(20, 20);
            else

            /*****************Footer area******************/
            if (footer != null)

                {

                    doc.PageNumber = i;
                    if (isPageNumberInFooter)
                    {

            // Flatten the PDF
            for (int i = 1; i <= doc.PageCount; i++)

                doc.PageNumber = i;
                doc.Flatten();

            var pdf = doc.GetData();
            doc.Clear();

            return pdf;

我还检查了其他解决方案，其中一个被接受与我的相似。因此无法解决问题。检查一下，它被接受，和我的相似：

#include <stdio.h>
#include <string.h>
#define INGREDIENT 4

int main()
{
    int pairs;
    int c[INGREDIENT]={0};
    char ingredient1[INGREDIENT][11];
    char ingredient2[INGREDIENT][11];
    scanf("%d", &pairs);
    int i,j,k;
    for (i = 0; i < pairs; i++)
    {
        for (j = 0; j <INGREDIENT; j++)
        {
            scanf("%s", ingredient1[j]);
        }
        for (j = 0; j <INGREDIENT; j++)
        {
            scanf("%s", ingredient2[j]);
        }
        for (k = 0; k <4; k++)
        {
            for (j = 0; j < 4; j++)
            {
                if(strcmp(ingredient1[k], ingredient2[j]) == 0)
                    ++c[i];
            }
        }
    }
    for (i = 0; i < pairs; i++)
    {
        if (c[i]>=2)
        {
            printf("similar\n");
        }
        else
            printf("dissimilar\n");
    }
    return 0;
}

Answer 1

感谢朋友，我发现问题是我已宣布

int c[INGREDIENT]={0}; where INGREDIENT = 4

但我试图超越4个元素的限制，每次变量'pair'大于4

for (i = 0; i < pairs; i++)
{
    if (c[i]>=2)

需要使用，可能是一个malloc函数。或者可能是calloc，因为我想将数组c初始化为0 ::

int* c;
c = (int*) calloc(pairs, sizeof(int));

也以：

结束

free(c);

CodeChef上的运行时错误：SIGSEGV
