Recursive Count Write a recursive function rc_count (L:List[int], x:int) -> int that takes a list L and an integer x. The function returns the number of occurrences of x in L. For example, rc_count([1,1,2,3], 1) returns 2 and rc_count([1,1,2,3], 4) returns 0. Your Answer: 1 # Put your answer here 2

Declaring and Defining the function

A set of statements, which performs a particular task is called a function. The program gains modularity by using function. The application is quite easy to understand, read, and edit when they are created with functions. The developer/programmer creates a function and uses main() to call the function. Once the function gets executed, the control is transferred to the main program.

Question

Recursive Count
Write a recursive function rc_count(L:List[int], x:int) -> int that takes a list L and an
integer x. The function returns the number of occurrences of x in L. For example,
rc_count([1,1,2,3], 1) returns 2 and rc_count([1,1,2,3], 4) returns 0.
