Задача “Blog”
September 14th, 2006 by OScar
Решая задачки с Ural State University Problem Set Archive, наткнулся на задачку Blog.
Вот преамбула:
The last time many users keep internet diaries – blogs. The users keep their diaries and occasionally read other’s. Those users like to count their virtual friends. A friend for them is anyone who reads their twaddle. Assume that a user reads another’s blog if he mentions the one in his diary.
