Team Collaborations

You are managing a list of teams where each team consists of members identified by unique ids. Sometimes, teams collaborate with each other, which means the members of those teams can be considered as one group. Write a program to find out how many distinct teams (groups of members) exist after all collaborations have been recorded. Input: The first line contains an integer c (1 <= c <= 1000), the number of collaborations. The next c lines contain two integers a and b (members of two collaborating teams). Output: Print the number of distinct teams after all collaborations. Example: Input: 5 1 2 2 3 4 1 5 6 6 5 Output: 3
