In the code segment below, assume that the ArrayList object numbers has been properly declared and initialized to contain [0, 2, 4, 5]. for (int k = numbers.size() - 1; k >= 0; k--) { if (numbers.get(k) > k) { System.out.print(k + " "); } } What, if anything, is printed as a result of executing the code segment?
Answer:
Result: C The output that will be printed will be: 3 2 1 If the program is executed, the loop runs in reverse. So it runs from 3 to 0. In the first iteration: at index 3 the corresponding number is 5, so since 5 is greater than present value of k.

Determine the binary encoding for a system that uses two’s complement of the base-10
quantities negative six and six for a digital system where all binary numbers are represented by four bits, one where all numbers are represented by eight bits (one byte).
Answer:
4 bits:
6 = 0110
-6 = 1010
8 bits:
6 = 00000110
-6 = 11111010
Explanation:
2's complement is easier to implement, because it only has one representation of 0 and starts counting backwards from the highest number you can represent with the available bits.
e.g.,
7 = 0111
6 = 0110
5 = 0101
4 = 0100
3 = 0011
2 = 0010
1 = 0001
0 = 0000
-1 = 1111
-2 = 1110
-3 = 1101
-4 = 1100
-5 = 1011
-6 = 1010
For 4 bits:
-6 = 01106 = 1010For 8 bits (1 byte):
-6 = 0000 + 0110 = 000001106 = 1111 + 1010 = 11111010What is binary encoding?Binary encoding can be defined as a standard technique that is designed and developed to convert data in plain text (source alphabets) to a form that is easily used by different operating systems (OS), especially through the use of a binary digit (bit) or two-symbol system.
The two’s complement of base-10.In Computer programming, two's complement of base-10 is generally easier to implement because it has a single representation of 0 only.
Decimal Two’s Complement Decimal Two’s Complement
0 0000 0 0000
1 1111 1111 -1 0000 0001
2 1111 1110 -2 0000 0010
3 1111 1101 -3 0000 0011
4 1111 1100 -4 0000 0100
5 1111 1011 -5 0000 0101
6 1111 1010 -6 0000 0110
7 1111 1001 -7 0000 0111
8 1111 1000 -8 0000 1000
For 4 bits:
-6 = 0110
6 = 1010
For 8 bits (1 byte):
-6 = 0000 + 0110 = 00000110
6 = 1111 + 1010 = 11111010

Identify science and technology policies that could be adapted or implemented in the Philippines?
Answer:
In the Philippines, universities dominate the research arena. So you have scientists who make research for the sake of research.
The private sector may or may not adopt the research. If a research in UP finds a molecule that may kill cancer, we are not sure whether that research will be adopted or not.
We are not sure if that research will be continued to actual creation of a medicine of cancer. This is because our scientists are working in universities and not in actual pharma companies.
In other countries, the scientists build their own companies. So their research go from drug development to actual manufacturing and marketing of medicines.
So when they start a research, you know that in the next 5 to 10 years, these scientists will produce drugs which the public can benefit from.
This is why the Philippine research is not thriving as it should. Our government should support our start ups.
When scientists are given grants for research, they should also be given grants to start their company. Unfortunately, start up grant is not a function of the DOST. It is of the DTI.

A game is played by moving a game piece left or right along a horizontal game board. The board consists of spaces of various colors, as shown. The circle represents the initial location of the game piece.
Yellow Black Green Green Red Yellow Black Black Yellow Black
The following algorithm indicates how the game is played. The game continues until the game is either won by landing on the red space or lost when the piece moves off either end of the board.
Step 1: Place a game piece on a space that is not red and set a counter to 0.
Step 2: If the game piece is on a yellow space, move the game piece 3 positions to the left and go to step 3. Otherwise, if the game piece is on a black space, move the game piece 1 position to the left and go to step 3. Otherwise, if the game piece is on a green space, move the game piece 2 positions to the right and go to step 3.
Step 3: Increase the value of the counter by 1.
Step 4: If game piece is on the red space or moved off the end of the game board, the game is complete. Otherwise, go back to step 2. If a game is begun by placing the game piece on the rightmost black space for step 1, what will be the value of the counter at the end of the game
Required:
If game piece is on the red space or moved off the end of the game board, the game is complete. Otherwise, go back to step 2. If a game is begun by placing the game piece on the rightmost black space for step 1, what will be the value of the counter at the end of the game?
The value of the counter of the given algorithm at the end of the game is; 4
How to solve Algorithms?
From the attached table, we see the algorithm of the given game.
Now, the black circle is initially under the column black.
From the given conditions, step 1 says since the space is not red we should set a counter to 0. Thus, the counter will be set to 0.
Since the game piece is under the black column, according to step 2, we will move the game piece 1 position to the left and go to step 3.
By moving one position to the left, the game piece will be under the yellow column. We now increase the counter by 1 to 1.
According to step 2, at yellow, we move the game piece 3 places to the left and it will land on yellow and we increase the counter to 2 and move 3 places to the left again to stop at green.
At green we increase the counter to 3 and then move two spaces to the left which is the left end of the board and we will increase the counter to 4 and the game will be complete according to step 4.
