Answer:

The answer is "2"

Explanation:

  • In the given java program code, a class WordScramble is declared, inside the class, a static method wordScramble is declared, that accepts two string parameter that is "rem and scr".
  • Inside the method a conditional statement is used in the if the block it checks rem variable value is empty so, it will add rem and scr value.  Otherwise, it will go to else block in this a loop is defined, which calls the method, which calculates rem length that is 2, and this method call two times to rearrange the values.
  • In the next step main method is defined that calls wordScramble method, which passes only one argument "ab" in its first parameter.
  • This method accepts one string value, in which there are two numbers   "a and b" that's why the method will run two times.

The processing of data in a computer involves the interplay between its various hardware components.
Ronch [10]

True.

Data processing involves the conversion of raw data and the flow of data through the Central Processing Unit and Memory to output devices. Each CPU in a computer contains two primary elements: the Arithmetic Logic Unit (ALU) and the control unit. The Arithmetic Logic Unit performs complex mathematical calculations and logical comparisons. On the other hand, the control unit accesses computer instructions, decodes them, and controls the flow of data in and out of the Memory, ALU, primary and secondary storage, and various other output devices.

Modems create an analog signal that carries digital data on it,

Given the dictionary, d, find the largest key in the dictionary and associate the corresponding value with the variable val_of_m
geniusboy [140]

Answer:

Here is the Python program:

d = {5:3, 4:1, 12:2}

val_of_max = d[max(d.keys())]

print(val_of_max)

Explanation:

The program works as follows:

So we have a dictionary named d which is not empty and has the following key-value pairs:

5:3

4:1

12:2

where 5 , 4 and 12 are the keys and 3, 1 and 2 are the values

As we can see that the largest key is 12. So in order to find the largest key we use max() method which returns the largest key in the dictionary and we also use keys() which returns a view object i.e. the key of dictionary. So

max(d.keys()) as a whole gives 12

Next d[max(d.keys())]  returns the corresponding value of this largest key. The corresponding value is 2 so this entire statement gives 2.

val_of_max = d[max(d.keys())] Thus this complete statement gives 2 and assigns to the val_of_max variable.

Next print(val_of_max) displays 2 on the output screen.

The screenshot of program along with its output is attached.
