Consider the below code: What would the output if dynamic scoping is used. Consider that execution of the code starts from main() function. #include <stdio.h> void main() { int x =3; A(x); B(x); C(x); } void A(int x) { printf("%d",x); } void B(int x) { int x =1; A(x); } void C(int x) { int x =2; B(x); }
PYTHON3 Complete the given function, encrypt_text that encrypts the variable text using the provided key by applying a modified version of Caesar’s Cipher with the following rules: The key will contain a word made up of the letters ‘u’ and ‘d’. The cipher will use the key to determine the direction of the shift, with a ‘u’ indicating that the character must be shifted upwards while a ‘d’ indicating a downward shift. The number of characters in the key will determine the number of positions to shift. The given text variable will only contain characters from the ASCII table with values between 32 and 126. If the key is invalid (empty string, contains characters other than u and d) or the text is invalid (empty string), no encryption occurs and the function returns the original text. If the text has more characters than the key, the key will loop through again to accommodate the additional text characters. An iterative approach should be used to solve this problem. Brute force…

You should submit a script file and a plain text output file (.txt) that contains the test output. Multiple file uploads are permitted. Don’t forget to include descriptive comments in your Python code. Your submission will be assessed using the following Aspects. Does the submission include the is_divisible function from Section 6.4 of the textbook? Does the submission implement an is_power function that takes two arguments? Does the is_power function call is_divisible? Does the is_power function call itself recursively? Does the is_power function include code for the base case of the two arguments being equal? Does the is_power function include code for the base case of the second argument being "1"? Does the submission include correct output for the five test cases?

In this challenge, the task is to debug the existing code to successfully execute all provided test files. Python supports a useful concept of default argument values. For each keyword argument of a function, we can assign a default value which is going to be used as the value of said argument if the function is called without it. For example, consider the following increment function: defincrement_by(n,increment=1):returnn+increment The functions works like this: >>>increment_by(5,2)7>>>increment_by(4)5>>> Debug the given function print_from_stream using the default value of one of its arguments. The function has the following signature: defprint_from_stream(n,stream) This function should print the first  values returned by get_next() method of stream object provided as an argument. Each of these values should be printed in a separate line. Whenever the function is called without the stream argument, it should use an instance of EvenStream class defined in…
