解题思路:

注意事项:

参考代码:

#include <stdio.h>

int main(){

   int a,b;

   int n;

   int i;

   int count;

   while(~scanf("%d", &n)){

      i = 1;

      count = 0;

      while(count >= 0){

         if(i%2 == 0){

            b = i+1;

            for(int j = i; j >= 1; j--){

               count++;

               if(count == n){

                  a = j;

                  count = -1;

                  break;

               }

            }

            b -= a;

         }

         else{

            b = i+1;

            for(int j = 1; j <= i; j++){

               count++;

               if(count == n){

                  a = j;

                  count = -1;

                  break;

               }

            }

            b -= a;

         }

         i++;

      }

      printf("%d/%d\n", b,a);

   }

   return 0;
