Which is the base case of the following recursion function: def mult3(n):    if n == 1:        return 3    else:        return mult3(n-1) + 3     else     n == 1

Use ONLY PyCharm, please.Thank you.

Ex. 01 : Recursion About So far, we have learned that we can perform repetitive tasks using loops. However, another way is by creating methods that call themselves. This programming technique is called recursion and, a method that calls itself within it's own body is called a recursive method. One use of recursion is to perform repetitive tasks instead of using loops, since some problems seem to be solved more naturally with recursion than with loops. To solve a problem using recursion, it is broken down into sub-problems. Each sub-problem is similar to the original problem, but smaller in size. You can apply the same approach to each sub-problem to solve it recursively. All recursive methods use conditional tests to either 1. stop or 2. continue the recursion. Each recursive method has the following characteristics: 1. end/terminating case: One or more end cases to stop the recursion. 2. recursive case: reduces the problem in to smaller sub-problems, until it reaches (becomes) the end…

Complete the following recursive function that returns the sum of all the numbers in a list that are positive and even numbers. Replace the bold text with the correct expression. #lang racket (define (positiveEvenNums 1st) (if (null? 1st) (if (THE CAR OF THE LIST IS POSITIVE AND EVEN) (+ (car 1st) (positiveEvenNums (cdr 1st))) (positiveEvenNums (cdr 1st))))) (positiveEvenNums '(-3 8 4 3 -2 0 5))
