### Question:
CDKMCS { public static List<List<CDKRMap>> getSubgraphMaps(IAtomContainer g1, IAtomContainer g2, boolean shouldMatchBonds, boolean shouldMatchRings, boolean matchAtomType) throws CDKException { return search(g1, g2, new BitSet(), getBitSet(g2), true, true, shouldMatchBonds, shouldMatchRings, matchAtomType); }  static boolean isIsomorph(IAtomContainer g1, IAtomContainer g2, boolean shouldMatchBonds, boolean shouldMatchRings, boolean matchAtomType); static List<List<CDKRMap>> getIsomorphMaps(IAtomContainer g1, IAtomContainer g2,
