Answer:

class Main {

public static void fillTable(int [][] t, int or, int oc) {

for(int r=0; r<t.length; r++) {

for(int c=0; c<t[r].length; c++) {

t[r][c] = Math.max(1+Math.abs(r-or), 1+Math.abs(c-oc));

}

public static void dumpTable(int [][] t) {

for(int r=0; r<t.length; r++) {

for(int c=0; c<t[r].length; c++) {

System.out.printf("%3d", t[r][c]);

}

System.out.println();

}

public static void main(String[] args) {

int origin_row = 3;

int origin_col = 2;

int[][] table = new int[5][4]; // rows|cols

fillTable(table, origin_row, origin_col);

dumpTable(table);

}

Explanation:

Above program does not contain input handling and exception handling, but it does contain the cleverness of calculating the cell values. I'm hoping you can add the input handling yourself?

There are four types of characteristics attributed to a flow: reliability, delay, jitter, and bandwidth. Explain how each of the

sergeinik [125]

Answer and Explanation:

Reliability is important because if the service lacks lacks reliability this could mean losing a packet or acknowledgement which then requires retransmission.

Delay can be tolerable in different degrees by applications, for example online chatting or conferences need to have the minimum delay possible.

Jitter is the variation in delay for packets belonging to the same flow.

High Jitter: difference between delays is large

Low jitter: difference between delays is small.

Bandwidth depends on the application. In video conferences, for example, there is a need to send million of bits per second to refresh a colour screen while sending a email may not reach even a million.

Use the Date object and the Array object to determine and diplay information about the current date on your webpage. Your output

Mnenie [13.5K]

Answer:

var today = new Date();
var dateComp = [];
dateComp[0] = today.getDate();
dateComp[1] = today.getMonth();
dateComp[2] = today.getFullYear();
switch(dateComp[1]){
case 0:
console.log("Jan " + dateComp[0] + "," + dateComp[2])
break;
case 1:
console.log("Feb " + dateComp[0] + "," + dateComp[2])
break;
case 2:
console.log("Mar " + dateComp[0] + "," + dateComp[2])
break;
case 3:
console.log("Apr " + dateComp[0] + "," + dateComp[2])
break;
case 4:
console.log("May " + dateComp[0] + "," + dateComp[2])
break;
case 5:
console.log("Jun " + dateComp[0] + "," + dateComp[2])
break;
case 6:
console.log("Jul " + dateComp[0] + "," + dateComp[2])
break;
case 7:
console.log("Aug " + dateComp[0] + "," + dateComp[2])
break;
case 8:
console.log("Sept " + dateComp[0] + "," + dateComp[2])
break;
case 9:
console.log("Oct " + dateComp[0] + "," + dateComp[2])
break;
case 10:
console.log("Nov " + dateComp[0] + "," + dateComp[2])
break;
case 11:
console.log("Dec " + dateComp[0] + "," + dateComp[2])
break;
}

Explanation:

The solution code is written in JavaScript.

Firstly, create a Date object (Line 1). The date object will automatically capture the current date and time.

Next create an array dateComp to hold the day, month and year (Line 3 -5). We use the getDate method to get current day, getMonth method for current month and getFullYear method for current year.

This is important to note that the getMonth method will return the value range from 0 - 11 with the Jan is represented as 0, Feb is 1 and so forth. Presume we intend to display the date using the format "month day, year", we can create a switch structure to check the month value which is range from 0 to 11. If month value is 0, generate string Jan + current day + "," + current year. We generate the date string based on different switch cases (7 - 44). We shall see the output similar to the date string as shown below:

Is it more costly to Andrew to go to graduate business school full time or part time if the tuition is the same for each? A. Par

andrezito [222]

Answer:

A. Part time

Explanation:

Since tuition is the same whether he goes part time or full time, in the long run he will end up paying tuition a greater number of times if he is a part time student.

2. Consider a 2 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of

allsm [11]

Answer:

program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

Explanation:

Finding number of instructions in A and B using time taken by the original processor :

The clock speed of the original processor is 2 GHz.

which means each clock takes, 1/clockspeed

= 1 / 2GH = 0.5ns

Now, the CPI for this processor is 1.5 for both programs A and B. therefore each instruction takes 1.5 clock cycles.

Let's say there are n instructions in each program.

therefore time taken to execute n instructions

= n * CPI * cycletime = n * 1.5 * 0.5ns

from the question, each program takes 1 sec to execute in the original processor.

therefore

n * 1.5 * 0.5ns = 1sec

n = 1.3333 * 10^9

So, number of instructions in each program is 1.3333 * 10^9

the new processor :

The cycle time for the new processor is 0.6 ns.

Time taken by program A = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.1 * 0.6ns

= 0.88 sec

Time taken by program B = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.4 * 0.6

= 1.12 sec

Now, program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

___ is an example of a calling statement.

Naddika [18.5K]

Answer:

printf("%f", roi(3, amt));

Explanation:

To call the function, we have to put the function name without return type and if the function have parameter then we have to pass the parameter without data type as well.

Let discuss the options:

Option A: float roi(int, double);

it is not a calling, it is used to declare the function. In calling, return type of the function like float and data type of the parameter does not pass like int, double.

Option B: printf("%f", roi(3, amt));

print is used to display the result, inside the print it call the function. It is correct way to call the function.

Option C: float roi( int yrs, double rate);

it is not a calling, it is used to declare the function. In calling, return type of the function like float and data type of the parameter does not pass like int, double.

Option D: float roi( int yrs, double rate)

Same reason as option C.

Therefore, the option B is correct option.
