Minimum spanning tree:In a given connected undirected graph G = (V, E) ,(U, v) represents the edge of the connection vertex u and vertex V , and W (u, v) represents the weight of this edge, if there is a subset of G and no loop graph, so that W

Basic ideas:Define node Set U, V (U = Node set that has been selected to join MST, V = not selected)1. Choose a node to join U2. Select an edge with the least edge, and his two nodes belong to U, V, and the node belonging to V is added to u3. Repeat

For example: If you enter: ( (1 + 2) * (3 + (4 * 5)) calculates the value of the arithmetic expression for the input string. We support the operator +,-, *,/, and a unary operation ABS, which can be used to obtain the value of this arithmetic
