First solution in Creative category for Backward String by drBobcat
def backward_string(val):
if len(str(val)) == 0:
return val
else:
return backward_string(str(val[1:])) + (str(val[0]))
if __name__ == '__main__':
print("Example:")
print(backward_string('val'))
# These "asserts" are used for self-checking and not for an auto-testing
assert backward_string('val') == 'lav'
assert backward_string('') == ''
assert backward_string('ohho') == 'ohho'
assert backward_string('123456789') == '987654321'
