Well knowing how the government is with security id go with A. as it makes a lot of sense unlike B and D and if they were looking for software the question would mention it
Answer:
See explaination
Explanation:
StackExample.java
public class StackExample<T> {
private final static int DEFAULT_CAPACITY = 100;
private int top;
private T[] stack = (T[])(new Object[DEFAULT_CAPACITY]);
/**
* Returns a reference to the element at the top of this stack.
* The element is not removed from the stack.
* atreturn element on top of stack
* atthrows EmptyCollectionException if stack is empty
*/
public T peek() throws EmptyCollectionException
{
if (isEmpty())
throw new EmptyCollectionException("stack");
return stack[top-1];
}
/**
* Returns true if this stack is empty and false otherwise.
* atreturn true if this stack is empty
*/
public boolean isEmpty()
{
return top < 0;
}
}
//please replace "at" with the at symbol
Note:
peek() method will always pick the first element from stack. While calling peek() method when stack is empty then it will throw stack underflow error. Since peek() method will always look for first element ffrom stack there is no chance for overflow of stack. So overflow error checking is not required. In above program we handled underflow error in peek() method by checking whether stack is an empty or not.
Answer:
Search for something that fits her needs
Explanation:
There are several approaches to problem solving, the approach that will be employed depends on our definition of the problem. Not all processes can be modeled by mathematical equations, some processes are simply theoretical and can be explained by simple logic.
If Allison does not find the needed equations among the available default equations, she can come up with an equation that addresses the process at hand. If she cannot come up with any, she can use other approaches that fit her needs to explain the required concept to the team.
Answer:
The content of the cell is called an absolute cell reference.
Explanation:
Ms-excel can hold a value or string or number or formulas in each cell.
The end-user can input the values to a cell and do any calculation by using inbuilt formulas and do the necessary calculation and get the output in the required cell
When end-user try to copy and paste the data to another cell he or she can use paste special option where he or she can select values, by selecting values to end-user is just copying the data not formula this is called absolute reference of the cell
By using paste special end users copy the image or Unicode also.
This process is called an absolute cell reference
To keep a desktop computer or a server powered up when the electricity goes off in addition to protection against power fluctuations, an <u>uninterruptible power supply (UPS)</u>, which contains a built-in battery, can be used.
<u>Explanation</u>:
An uninterruptible power supply (UPS) is a device that allows a computer or server powered up for a short time, when the electricity goes off. UPS device also provides uninterrupted service during power fluctuation.
A battery is inbuilt in the UPS and provides power for few minutes to the computer to shut down it in a proper manner.
UPS is available at affordable cost and can be maintained at low cost compared to generators.
