Corrupt File Recovery

In a file recovery application, you track clusters of corrupt blocks within a large file. Each cluster may be connected directly to another cluster. Given a set of connections between clusters, identify the maximum number of clusters that can be recovered from a single corrupt block. Input Format: - An integer n representing the number of clusters. - The following n lines contain two integers u and v per line, representing a connection between corrupt blocks (zero-indexed). Input ends with 'END'. Output Format: - Print a single integer representing the maximum number of clusters that can be recovered from one corrupt block. Example Input: 5 0 1 1 2 2 3 3 4 END Example Output: 5
