### Question:
Wcc extends Algorithm<Wcc, DisjointSetStruct> { public static MemoryEstimation memoryEstimation(boolean incremental) { return MemoryEstimations .builder(Wcc.class) .add("dss", HugeAtomicDisjointSetStruct.memoryEstimation(incremental)) .build(); } Wcc(
        Graph graph,
        ExecutorService executor,
        int minBatchSize,
        WccBaseConfig config,
        ProgressLogger progressLogger,
        AllocationTracker tracker
    ); static MemoryEstimation memoryEstimation(boolean incremental); @Override DisjointSetStruct compute(); @Override Wcc me(); @Override void release(); double threshold();  }### Answer:
