code: public void put(int i, double value) {
  		if (i < 0 || i >= N) throw new IllegalArgumentException("Illegal index " + i + " should be > 0 and < " + N);
  		if (value == 0.0) symbolTable.delete(i);
  		else              symbolTable.put(i, value);
  	}
docs: Setter method (should it be renamed to set?)
  
  @param i set symbolTable[i]
  @param value
