Project Collaborations

In a company, employees can form teams to work on projects if they have previously collaborated on at least one project. Given a list of pairings representing collaboration between employees on projects, determine how many distinct teams can be formed. Input: - The first line contains an integer n (1 <= n <= 100), the number of employees. - The second line contains an integer m (0 <= m <= n*(n-1)/2), the number of collaboration pairs. - Each of the following m lines contains two integers a and b, which denote that employee a collaborated with employee b. Output: - Print the number of distinct teams that can be formed. Example: Input: 4 3 0 1 1 2 3 3 Output: 2
