Given a string, return a string where for every char in the original, there are two chars.

Here's a Python code snippet that doubles every character in a given string: ``` python def double_char(string): doubled_string = '' for char in string: doubled_string += char * 2 return doubled...

Prove that if a1, a2,..., an are n ≥ 2 integers such that ai ≡ 1 (mod 3) for every integer i (1 ≤ i ≤ n), then a1a2 ··· an ≡ 1 (mod 3)

2023-04-24 上传
That is, if a1, a2, ..., ak are integers such that ai ≡ 1 (mod 3) for every integer i (1 ≤ i ≤ k), then a1a2···ak ≡ 1 (mod 3). Now, consider n = k + 1. We have ak+1 ≡ 1 (mod 3), since ak+1 ...

6.21 Consider a system running ten I/O-bound tasks and one CPU-bound task. Assume that the I/O-bound tasks issue an I/O operation once for every millisecond of CPU computing and that each I/O operation takes 10 milliseconds to complete. Also assume that the context-switching overhead is 0.1 millisecond and that all processes are long-running tasks. Describe the CPU utilization for a round-robin scheduler when: a. The time quantum is 1 millisecond b. The time quantum is 10 milliseconds

2023-06-09 上传
If the time quantum is 1 millisecond, the CPU utilization for a round-robin scheduler will be approximately 90.91%. This is because each I/O-bound task will consume 1 millisecond of CPU time and 10 ...

用到以下类实现The division of responsibility between the different classes is as follows. - Die: Responsible for handling randomly generated integer values between 1 and 6. - DiceCup: Handles five objects (dice) of class Die. Has the ability to bank and release dice individually. Can also roll dice that are not banked. - ShipOfFoolsGame: Responsible for the game logic and has the ability to play a round of the game resulting in a score. Also has a property that tells what accumulated score results in a winning state, for example 21. - Player: Responsible for the score of the individual player. Has the ability, given a game logic, play a round of a game. The gained score is accumulated in the attribute score. - PlayRoom: Responsible for handling a number of players and a game. Every round the room lets each player play, and afterwards check if any player has reached the winning score. 3. Implementation

The `Player` class represents a player and has a `play_round()` method that plays a round of the game for that player, using a `DiceCup` object and following the game rules. Finally, the `PlayRoom` ...

Use the method find_all() to find all hyperlinks in soup, remembering that hyperlinks are defined by the HTML tag but passed to find_all() without angle brackets; store the result in the variable a_tags. The variable a_tags is a results set: your job now is to enumerate over it, using a for loop and to print the actual URLs of the hyperlinks; to do this, for every element link in a_tags, you want to print() link.get('href').

# Enumerate over the a_tags using a for loop for link in a_tags: # Print the URL of each hyperlink using link.get('href') print(link.get('href')) ``` In this code, we use the `find_all()` method on...

Write a C function void words(const char str[ ]) that takes a zero-terminated string as an input, and shows every word of the string on a different line. A word is defined as a sequence of non-space character separated by one or more space characters.

2023-07-10 上传
You can use this function to show every word of a string on a different line. For example: ```c int main() { const char str[] = "Hello world! This is a test."; words(str); return 0; } ``` Output:...
