Social Network Friendships

In a social network, users can be friends with other users. You are given a list of friendships represented as pairs of integers (a, b), where a is friends with b. Write a function that finds the size of the largest connected group of users, where a connected group consists of users that are directly or indirectly friends. Input format: The first line contains an integer n (1 <= n <= 100), representing the number of friendships. The next n lines contain two integers a and b representing a friendship between user a and user b. Output format: An integer representing the size of the largest connected group of users. Example: Input: 5 0 1 1 2 2 3 4 5 3 4 Output: 5
