If we just check that the left side is empty, we have confirmed that a problem occurs in the corner entering the inside, and to prevent this, we checked again. | cs1qa | null | null | null | null | null | Question:
How did you determine if it was a window?
Is there a reason you're so salty?
Code:
from cs1robots import *
# Your code must work for both of the worlds below.
# load_world('worlds/rain1.wld')
load_world('worlds/rain2.wld')
# Initialize your robot at the door of the house.

result = [0, 1]
while True:
result.append(result[-1]+result[-2])
if result[-1] >= upper_bound:
result.remove(result[-1])
return(result)
print(fibonacci(1000))
| 2 | 7 | reasoning | It is to repeat until the upper_bound is exceeded, and when the condition is satisfied, it is finished with return. | cs1qa | null | null | null | null | null | Question:
