for(int i=0;i<len;i++)
{
ans+=pow(((int)(buf[i]-'0')),3);
}
while accepted in this way
for(int i=0;i<len;i++)
{
ans+=(buf[i]-'0')*(buf[i]-'0')*(buf[i]-'0');
}
WHY?!!!!
Is this a bug on judge or bug in function?!!
the compiler is g++ why not try this
ans+=round(pow(((int)(buf[i]-'0')),3)); | | Who has TIME LIMIT (+) | Виктор Крупко | 1292. Марсианские космобазы | 29 апр 2014 13:50 | 8 | 1000=1^3+0^3+0^3+0^3=1
1=1^3=1
IF THE DISTANCE BETWEEN TWO POINTS = 1 THAT FOLLOWING TOO WILL BE 1.
USE BREAK It is wrong.
"Oh, by the way! The value of SMK is always divisible by 3. It’s normal for Martians – all their numbers are divisible by 3." On another if the previous number is equal to next that break f(153)=1^3+5^3+3^3=1+125+27=153
=)) That's really so! :) Thank you! I've got AC! Its my solution:

Edited by moderator 06.12.2019 20:30 Your prog get AC, but
look at this test:
1
33333 313 1
log of my prog:
2) 55
3) 250
4) 133
5) 55
6) 250
7) 133
8) 55
9) 250
10) 133
11) 55
12) 250
13) 133
14) 55
15) 250
16) 133
17) 55
18) 250
19) 133
20) 55
21) 250
22) 133
23) 55
24) 250
25) 133
26) 55
27) 250
-----
there is period! And you never get dist[j]==dist[j-1]
And your prog get TLE on my test:
||| 33333
1) ||| 33333 313 1
2) ||| 33333 313 1
3) ||| 33333 313 1
4) ||| 33333 313 1
5) ||| 33333 313 1
i) ||| 33333 313 1
33333) ||| 33333 313 1
But there is no such tests => AC. =)

Edited by moderator 06.12.2019 20:31 313 isn't divisible by 3. | | Statement | Sevenk | 1292. Марсианские космобазы | 6 ноя 2009 16:58 | 2 | So if the distance from the (I-1)-th to I-th stations is X, than the distance between I-th and (I+1)th stations is F(X).
than->then? | | This description must be wrong! | Zieve Cheng | 1292. Марсианские космобазы | 23 май 2004 14:59 | 2 | (for example F(12) = 13 + 23 = 9).
The right must be:(for example F(12) = 1^3+2^3=9). |
