Library Connections

In a library, books are represented by integers from 0 to n-1. Given a list of connections that indicate how books are related, determine the number of distinct groups of related books in the library. Input Format: - The first line contains an integer n (1 ≤ n ≤ 100). - The second line contains an integer m (0 ≤ m ≤ 10^4) representing the number of connections. - The following m lines each contain two integers a and b (0 ≤ a, b < n) representing a connection between book a and book b. Output Format: - Print the number of distinct groups of related books. Example: Input: 3 2 0 1 1 2 Output: 1
