Consider the following code segment: ArrayList nums = new ArrayList ();
nums. add(10);
nums. add(20);
nums. add(30);
nums. add(40);
nums. add(50);
int x = nums. remove(3);
int y = x + nums. remove(0);
int z = x + y;
nums. add(2, z);
Which of the following represents the value of nums after the code segment has been executed?

[20, 40, 90, 50]

[10, 20, 30, 40, 50]

[20, 30, 90, 50]

[20, 40, 50, 90]

[20, 30, 80, 50]

What engine component is shown in the above figure?

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system. currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system. currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system. currenttimemillis() just after the end of the algorithm as the elapsed time.

4. what is the reason for including the following code snippet in the header file animal. h? #ifndef animal_h #define animal_h class animal { public: animal(); animal(double new_area_hunt); void birth(); void hunt(double new_area_hunt); void death(); double get_area_hunt() const; private: double area_hunt; }; #endif
