Fill in the blank in the function below so that the function prints the integers from 1 down to the integer value it was given for N. That is, if the function is executed with the value of N being -3, it should print 1, 0, -1, -2, -3.def xxx(N): if (_________): xxx(N + 1) print(N)
Question
Fill in the blank in the function below so that the function prints the integers from 1 down to the integer value it was given for N. That is, if the function is executed with the value of N being -3, it should print 1, 0, -1, -2, -3.def xxx(N): if (_________): xxx(N + 1) print(N)
Solution
The blank in the function should be filled with "N <= 0". Here is the complete function:
def xxx(N):
if (N <= 0):
xxx(N + 1)
print(N)
This function uses recursion to print the numbers from 1 down to N. The base case for the recursion is when N is greater than 0, at which point the function stops calling itself. If N is less than or equal to 0, the function calls itself with N + 1 and then prints the current value of N. This means that the numbers are printed in ascending order from 1 to N.
