Here it is my code!

#include <stdio.h>

#define  N 100
#define  G 10
#define  Y 20

char  a[N][N] = {0}, n, b[N] = {0};


int  main()
{
  int  i, j, k, t;

  scanf("%d", &n);
  for  (i = 0;  i < n;  ++i) {
    scanf("%d", &k);
    for  (j = 0;  j < k;  ++j) {
      scanf("%d", &t);
      a[i][t-1] = 1;
    }
  }

  for  (i = 1;  i < n;  ++i) {

    for  (j = 0;  j < i;  ++j)
      if  (a[i][j] == 1) {
        if  (b[j] < 0)  {
          b[i]--;
          b[j]++;
          a[i][j] = Y;
          a[j][i] = G;
        }

        if  (b[j] > 0)  {
          b[i]++;
          b[j]--;
          a[i][j] = G;
          a[j][i] = Y;
        }
      }

    for  (j = 0;  j < i;  ++j)
      if  (a[i][j] == 1) {
        if  (b[i] >= 0)  {
          b[i]--;
          b[j]++;
          a[i][j] = Y;
          a[j][i] = G;
          continue;
        }

        if  (b[i] < 0)  {
          b[i]++;
          b[j]--;
          a[i][j] = G;
          a[j][i] = Y;
          continue;
        }
      }
  }

  for  (i = 0;  i < n;  ++i) {
      for  (j = 0;  j < n;  ++j)
        if  (a[i][j] == G)  printf("G ");
        else  if  (a[i][j] == Y)  printf("Y ");
      printf("\n");
    }

  return 0;
}


And here it is tricky test:
6
1 4
2 4 6
1 5
4 1 2 5 6
2 3 4
2 2 4
