Network Emergency Response

In a network of computers, each computer can directly communicate with others. You need to determine how many separate networks are present in the system if some computers are not directly connected to others. Write a program that reads a list of connections between computers and outputs the number of distinct networks. Input Format: - The first line contains an integer n (number of computers). - The second line contains an integer m (number of connections). - The next m lines each contain two integers a and b representing a connection between computer a and b. Output Format: - Print the number of distinct networks. Example: Input: 5 3 1 2 2 3 4 5 Output: 2
