### Re: 10333 Wrong Anwers, But The Output is Correct

That is OK with the Output part of the problem, but their test output simply writes:yayas wrote:Code: Select all

`printf("Tower : #%d\n",tm);`

Code: Select all

```
Tower #n
```

Sorry if I sounded rude, Adrian, I meant it's fishy that 95% of people didn't find out that both LIS and simple greedy are fundamentally incorrect. :wink: Well, it seems like I have got AC again, by modifying the greedy algorithm. It now uses construction approach: 1. start with an empty stack 2. in...

This is not in fact a LIS problem, but rather one that is solved with greedy algorithm. Before using LIS, I suppose that you are sorting the input, boiling down to a greedy algorithm where sorting criterion is the cost function. I've got AC on greedy algo by maximizing "remaining strength" which is ...

Well, I finally got it AC in only 0.002 sec, without use of big number division. To solve the problem, you got to transform the expression to the form: D(t, a, b) = sum(i=0, a/b - 1) (t^b)^i, where a%b=0 This sum can be further solved recursively: D(t, a, b) = f(t^b, a/b) f(x, 1) = 1 f(x, 2k) = (1 +...

I've got TLE as well, and here's what I did: 1. checked for special cases (b < a, b = 0, a = 0 -- although problem text says POSITIVE integers --, t = 1) - in each of these cases, result is either integer 0, or is not an integer 2. checked whether (a - b) * log10(t) > 99 - in this case result is has...
