There was a problem hiding this comment. sizeof(int*) тут очень внезапно, sizeof(Node) имелось в виду, скорее всего |

There was a problem hiding this comment. nodesCount вместо 6, скорее всего |

There was a problem hiding this comment. Как я понял, это сильно недописанная попытка сделать dfs. Но если он рекурсивный, то list (очередь рассматриваемых вершин?) не нужен, мы ходим просто по соседям, а если нерекурсивный, то не нужен рекурсивный вызов. И в любом случае, нужно множество уже посещённых вершин. И тогда вся задача своидтся к "пока есть непосещённые вершины, берём первую из них, гоним dfs, все посещённые при этом вершины складываем в новую компоненту связности" |
