Hint: getting slices of the lists every time costs you a lot of time.

Also, please try describing your approach instead of posting the full code on the forum in the future.

#173

Hi, my code don’t work for three last tests but for the fourth even the if statement is false, the IDE is still going through it

if min(v, key=v.get) != 1:
    print(some code)
else:
    print(0)

print(v,min(v, key=v.get) != 5, file=sys.stderr, flush=True)

It print some code (a int that is not 0)
The debug command return this: {1: '3', 2: '4', 3: '7', 4: '9', 5: '10'} False

#174

That’s because the values are strings. ‘10’ < ‘3’ is True (if those are integers instead of strings, then 10 > 3 is True).

#175

Hi, my code work with all examples, but can’t validate the “Varied (1 5 4 10 8 4 5 42 41)”.
I tried to used it as a custom playtest and -4 as the result (8-4). Its work on the ide but when i submit it fail. Is the result -4 or i messed up in the process ?

#176

The answer is -6 (10 → 8 → 4) instead of -4.

#178

u can do it in time complexity O(n), with O(n**2) test 5 fails, unless you use a little trick that optimizes it, in which case even python will go through just fine. i recommend u find the best time complexity, thats the only real good answer and its not too hard to find(im missing run time from the site:/)
