Question
Design a recursive function that accepts an integer argument, n, and prints the numbers 1 up through n.
Answer
The following program code is used to a recursive function that accepts an integer argument, n, and prints the numbers 1 up through n:
#Create a function name, printNumbers
def printNumbers(num):
if num > 1:
# Recursive call
printNumbers(num - 1)
# Print the current value of n
print(num)
# Test the function
n = int(input("Enter a positive integer: "))
print("Numbers 1 to", n)
printNumbers(n)
Executed Output:
Enter a positive integer: 25
Numbers 1 to 25
