### Question:
BaseUInt32Value implements UInt32Value<T> { @Override public T multiplyMod(T value, UInt32 modulus) { return multiplyMod(value.toUInt32(), modulus); } protected  BaseUInt32Value(UInt32 value, Function<UInt32, T> ctor); protected  BaseUInt32Value(int value, Function<UInt32, T> ctor); protected  BaseUInt32Value(BigInteger value, Function<UInt32, T> ctor); @Override T add(T value); T add(UInt32 value); @Override T add(int value); @Override T addMod(T value, UInt32 modulus); T addMod(UInt32 value, UInt32 modulus); @Override T addMod(long value, UInt32 modulus); @Override T addMod(long value, long modulus); @Override T subtract(T value); T subtract(UInt32 value); @Override T subtract(int value); @Override T multiply(T value); T multiply(UInt32 value); @Override T multiply(int value); @Override T multiplyMod(T value, UInt32 modulus); T multiplyMod(UInt32 value, UInt32 modulus); @Override T multiplyMod(int value, UInt32 modulus); @Override T multiplyMod(int value, int modulus); @Override T divide(T value); T divide(UInt32 value); @Override T divide(int value); @Override T pow(UInt32 exponent); @Override T pow(long exponent); @Override T mod(UInt32 modulus); @Override T mod(int modulus); @Override int compareTo(T other); int compareTo(UInt32 other); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString(); @Override UInt32 toUInt32(); @Override Bytes toBytes(); @Override Bytes toMinimalBytes();  }### Answer:
