I'm sure I got WA because of reading string.
Here is my code to read string :
...
fscanf(stdin,"%d\n",&m) ;
for(int i=0;i<m;i++) {
char s[1000] ;
int j = 0 , k = 0 ;
fscanf(stdin,"%s",&s) ;
while ( s[j] != ',' ) a[i].x = a[i].x * 10 + s[j++] - 48 ;
j++ ;
while ( s[j] != ':' ) a[i].y = a[i].y * 10 + s[j++] - 48 ;
j++ ;
while (j < strlen(s) ) {
while ( s[j] != '-' ) b[i][k] = b[i][k] * 10 + s[j++] - 48 ;
j++ ;
while ( j < strlen(s) && s[j] != ',' ) c[i][k] = c[i][k] * 10 + s[j++] - 48 ;
k++ ;
if ( s[j] == '\n' ) { j++ ; break ; }
j++ ;
}
deg[i] = k ;
}
Use the Force, Luk. Here is my code for reading input.

scanf("%d\n",&n);
int i;
int id,x,y,r;
for (i = 0 ; i<n ; i++){
scanf("%d,%d:",&x,&y);
while (true){
scanf("%d-%d",&id,&r);

a[id][cnt[id]].x = x;
a[id][cnt[id]].y = y;
a[id][cnt[id]].r = r;
cnt[id]++;
char ch;

ch = getc(stdin);
if (ch!=',') break;
}

}

or:
for (int i=0; i<m; i++){
char buf;
cin >> tmp.x >> buf >> tmp.y;
while ((buf=cin.get())!='\n' && buf!=EOF){
int id;
cin >> id >> buf >>tmp.r;
a[id].push_back(tmp);
}
}
