Merge Employees

You have a list of employee pairs who are considered to be in the same team. Given a list of these pairs, determine the number of distinct teams formed by merging. Each employee is represented by a unique ID (0-indexed). Your task is to return the number of distinct teams after processing all pairs. Input format: - The first line contains an integer n, the number of employees. - The next line contains an integer m, the number of pairs. - The subsequent m lines each contain two integers a and b, representing that employees a and b are in the same team. Output format: - A single integer representing the number of distinct teams. Example: Input: 5 4 0 1 1 2 3 4 0 3 Output: 2
