Answer:
RAX = 333000h (16 bits with preceding zeros removed)
RDX = 20h (also 16 bits with preceding zeros removed)
Explanation:
The "div" opcode in the assembly language source code is used to divide operands. It accepts a divisor ( the denominator) and divides the content of the AX register. The result is saved in the AX register while the remainder (if any) is saved in the DX register. If the DX register holds any data, the data is replaced with the divisor remnant.
The code above divides the content of the RAX register with the divisor variable and saves the result and remainder in the RAX and RDX respectively.
It mainly just depends on if you "misuse" them.
Answer:
// program in Python.
#read year
i_year=int(input("Please Enter a year:"))
#check leap year
if((i_year % 4 == 0 and i_year % 100 != 0) or (i_year % 400 == 0)):
print("{} is a leap year.".format(i_year))
else:
print("{} is not a leap year.".format(i_year))
Explanation:
Read year from user and assign it to variable "year".If year is completely divisible by 4 and not divisible by 100 or year is completely divisible by 400 then year is leap year otherwise year is not a leap year.
Output:
Please Enter a year:2003
2003 is not a leap year.
Answer:
- public class FindDuplicate{
-
- public static void main(String[] args) {
- Scanner input = new Scanner(System.in);
-
- int n = 5;
- int arr[] = new int[n];
-
- for(int i=0; i < arr.length; i++){
- int inputNum = input.nextInt();
- if(inputNum >=1 && inputNum <=n) {
- arr[i] = inputNum;
- }
- }
-
- for(int j =0; j < arr.length; j++){
- for(int k = 0; k < arr.length; k++){
- if(j == k){
- continue;
- }else{
- if(arr[j] == arr[k]){
- System.out.println("True");
- return;
- }
- }
- }
- }
- System.out.println("False");
- }
- }
Explanation:
Firstly, create a Scanner object to get user input (Line 4).
Next, create an array with n-size (Line 7) and then create a for-loop to get user repeatedly enter an integer and assign the input value to the array (Line 9 - 14).
Next, create a double layer for-loop to check the each element in the array against the other elements to see if there is any duplication detected and display "True" (Line 21 - 22). If duplication is found the program will display True and terminate the whole program using return (Line 23). The condition set in Line 18 is to ensure the comparison is not between the same element.
If all the elements in the array are unique the if block (Line 21 - 23) won't run and it will proceed to Line 28 to display message "False".
Answer:
import java.util.Arrays;
public class swap{
public static void main(String []args){
int [] arr = {2,4};
swapValues(arr);
}
public static void swapValues(int[] values){
int temp;
System.out.println(Arrays.toString(values));
temp=values[0];
values[0]=values[1];
values[1] =temp;
System.out.println(Arrays.toString(values));
}
}
Explanation:
In the program above, we created the method swapValues that receives an array of integers as parameters. in the method definition, we created a temp variable that is used to swapp the element at index 0 and index 1. Java's Arrays.to string method is used to print the array before and after the swap.
