GateTranslator extends SolverDecorator<ISolver> { public IConstr[] it(int y, int x1, int x2) throws ContradictionException { IConstr[] constrs = new IConstr[3]; IVecInt clause = new VecInt(5); clause.push(-y).push(-x1).push(x2); constrs[0] = processClause(clause); clause.clear(); clause.push(x1).push(y); constrs[1] = processClause(clause); clause.clear(); clause.push(-x2).push(y); constrs[2] = processClause(clause); return constrs; } GateTranslator(ISolver solver); IConstr gateFalse(int y); IConstr gateTrue(int y); IConstr[] ite(int y, int x1, int x2, int x3); IConstr[] it(int y, int x1, int x2); IConstr[] and(int y, IVecInt literals); IConstr[] and(int y, int x1, int x2); IConstr[] or(int y, IVecInt literals); IConstr[] halfOr(int y, IVecInt literals); IConstr[] not(int y, int x); IConstr[] xor(int y, IVecInt literals); IConstr[] iff(int y, IVecInt literals); void xor(int x, int a, int b); void fullAdderSum(int x, int a, int b, int c); void fullAdderCarry(int x, int a, int b, int c); void additionalFullAdderConstraints(int xcarry, int xsum, int a,
            int b, int c); void halfAdderSum(int x, int a, int b); void halfAdderCarry(int x, int a, int b); void optimisationFunction(IVecInt literals, IVec<BigInteger> coefs,
            IVecInt result);  }### Answer:
