The Linux script detects that the local link specifies whether the IP segment is unblocked, detects the specified IP through the ping command, detects the command execution result, and if 0 is unblocked, if 1 indicates that the network is unblocked, except that the specified machine disables the ping command. The code is as follows:#!/bin/bash#For N in ' seq 121

The goal of the provincial government's "unblocked project" is to enable road traffic between any of the two villages in the province (but not necessarily directly connected roads, as long as they can be reached indirectly through the highway). After a survey, the resulting statistical tables list the costs of several roads that are likely to build roads. You are now asked to write a program to calculate the minimum cost of the province's smooth need.

The problem of dynamic connectivity is also found in general use and solution. The key is to find out the number of isolated points, the number of roads to be built is the number of isolated points-1. There is the result of the output, you should pay attention to how to input.and 3 m
