Question
Transcribed Image Text:### Recursive Function to Sum Integers
**Problem Description:**
Using recursion, write a function `sum` that takes a single argument `n` and computes the sum of all integers between 0 and `n` inclusive. Do not write this function using a while or for loop. Assume `n` is non-negative.
#### Function Definition Template:
```python
def sum(n):
"""
Using recursion, computes the sum of all integers between 1 and n, inclusive.
Assume n is positive.
>>> sum(1)
1
>>> sum(5) # 1 + 2 + 3 + 4 + 5
15
"""
*** YOUR CODE HERE ***
```
**Key Points:**
- Use of recursion to solve the problem.
- The function should correctly handle positive integers for `n`.
- Example calculations provided for `sum(1)` and `sum(5)`.
This task is part of learning recursive methods to solve mathematical problems programmatically.

Print out a message "Entering <function_name>" as the first executed statement of each function. Perform the code to test whether every element of the array is a Prime number. Print out a message "Leaving <function_name>" as the last executed statement before returning from the function. Remember - there will be nested loops for the iterative function and there can be no loops at all in the recursive function....arrow_forwardPython: How do I create a recursive function asterisk with both recursive and base cases? so for n=3, you would have below; *** ** * code that I have: for i in range(n): print("*",end="")arrow_forward
