You don't have to iterate over all N integers in fizzbuzz. Just increment the smallest by its own factor x
or y
:
from sacred import Experiment
ex = Experiment('fizzbuzz')
@ex.config
def my_config():
x = 10
y = 15
n = 100
@ex.automain
def main(x, y, n):
i, j = x, y
window = 1
while i <= n or j <= n:
# _min = min(i, j)
# if window < m:
# print(*range(window, _min), end=' ')
# window = _min + 1
if i == j:
print('FizzBuzz', end=' ')
i += x
j += y
elif i < j:
print('Fizz', end=' ')
i += x
else:
print('Buzz', end=' ')
j += y
print()
Note: I commented
print(*range(window, _min), end=' ')
because this will print all integers (which is linear), hiding the performance improvement.
Anyways, executing your code with the following parameters takes 33 seconds:
python fizzbuzz.py with x=13 y=7 n=10000000 -F ./logs/fizzbuzz/
"start_time": "2018-08-28T02:19:37.457346",
"stop_time": "2018-08-28T02:20:10.759150"
While the code above takes only 22 seconds:
python fizzbuzz.py with x=13 y=7 n=10000000 -F ./logs/fizzbuzz/
"start_time": "2018-08-28T02:20:24.905657",
"stop_time": "2018-08-28T02:20:47.376358"
