Python Coding Challange - Question with Answer (01140425)

 

Explanation step-by-step:

1. Function Definition:

   
   def printArr(arr, index):

   This defines a function called printArr that takes:

   • arr: a list of elements

   • index: the current position in the list to print

2. Base Condition (to stop recursion):

   
   if(index < len(arr)):

   This checks if the index is still within the bounds of the list. If not, the function stops (ends recursion).

3. Print the current element:

   
   print(arr[index])

   This prints the element at the current index.

4. Recursive Call:

   
   printArr(arr, index+1)

   This calls the function again, with index+1, to print the next element.

Sample Execution:

Given:

arr = [1, 3, 5, 7]
printArr(arr, 0)

Here's what happens:

Call	Output
printArr(arr, 0)	1
printArr(arr, 1)	3
printArr(arr, 2)	5
printArr(arr, 3)	7
printArr(arr, 4)	(stops, since 4 >= len(arr))

---

✅ Output:

1
3
5
7
