Question no. 04: Consider the Alphabet E = {a, b, c, d}. Write down the all types of regular expressions from the given alphabet
Use python
A problem that is defined recursively must have:- O a. The Definition O b. Base Case Oc. Range condition for variables Od All of the above
When a recursive function is run, there is an additional demand placed on the memory of the computer and the amount of time it takes to run the programme.
The code is already given above. Problem: Using PYTHON, create a code that asks you to enter three numbers: a, b, and x. Create a recursive function that takes in 3 inputs and prints the multiples of x in the range [a,b] V a and b will serve as lower and upper bounds of the range where the multiples of x will be searched on. v if x is odd, print the multiples in ascending order. V if x is even, print the multiples in descending order. The value of input a will always be less than or equal to input b. The difference between a and b will be limited to a maximum of 200 to avoid Python's "maximum recursion depth exceeded in comparison" error.
