Print Even and Odd Index Characters of a String using recursion
To print the even and odd index characters of a string using recursion in Python, we can define a recursive function that traverses the string and prints characters at even and odd indices. Here’s the Python program to achieve this:
Python
def print_even_odd_chars(string, index=0, even=True): # Recursive function to print even and # odd index characters of the string if index >= len(string): return if even and index % 2 == 0: print(string[index], end=' ') elif not even and index % 2 != 0: print(string[index], end=' ') print_even_odd_chars(string, index + 1, even)if __name__ == "__main__": input_string = "w3wiki!" print("Even Index Characters:") print_even_odd_chars(input_string, even=True) print("\nOdd Index Characters:") print_even_odd_chars(input_string, even=False) |
Output:
Even Index Characters:
G e s o g e s
Odd Index Characters:
e k f r e k !
