413 Up and Down Sequences

Post by C8H10N4O2 » Wed Apr 17, 2002 5:35 am

Can anyone help me figure out what is wrong with my code? It works for all the standard tests I can think of. ::This is a repost::
[cpp]#include <cstdio>
#include <vector>
#include <cstring>

using namespace std;

const int UP=1;
const int DOWN=2;
const int UK=3;
int Trend,LastTrend,C,LD,LU,NU,ND;
vector<int> X;

double r(double v)
{
return double(int((v)*1000000+0.5))/1000000;
}

void FU()
{
LU+=C;
NU++;
}

void FD()
{
LD+=C;
ND++;
}

void main()
{
char B[1000],*P;
int i,N;

while(gets(B)!=NULL)
{
X.clear();
P=strtok(B," ");
while(P)
{
sscanf(P,"%d",&N);
X.push_back(N);
P=strtok(NULL," ");
}
X.pop_back();
if(X.size()>0)
{
Trend=UK;
LastTrend=UK;
C=0;
LU=0;
LD=0;
NU=0;
ND=0;
for(i=1;i<X.size();i++)
{
LastTrend=Trend;
if(X>X[i-1]) Trend=UP;
if(X<X[i-1]) Trend=DOWN;
if(Trend!=LastTrend)
{
if(LastTrend!=UK)
{
if(LastTrend==UP)
FU();
else
FD();
C=0;
}
}
C++;
}
if(Trend==UP) FU();
if(Trend==DOWN) FD();
if(NU==0)NU++;
if(ND==0)ND++;
printf("Nr values = %d: %.6f %.6fn",X.size(),r(double(LU)/NU),r(double(LD)/ND));
}
else
{
break;
}
}
}[/cpp]

I got your program Accepted. Don't use your r function, with %.6f the values are already rounded. And you should perhaps check your mailer settings, because the output line is very long.

Thanks a lot. I just found out that my ISP's mail server is horribly distorting my code. I am resubmitting a lot of stuff. It wasn't on my end:P

your program didn't pass even sample input, have you noticed it?

this is your incorrect test case:
4 4 4 3 3 3 4 0
it should be
Nr values = 7: 1.000000 5.000000
but you have
Nr values = 7: 3.000000 5.000000

and here's more test cases for those who have difficulty solving it:

INPUT

Code: Select all

1 2 3 0
3 2 1 0
1 2 3 2 1 0
2 2 2 2 3 0
4 4 4 4 3 0
4 4 4 3 3 3 3 0
4 4 4 3 3 3 4 0
5 5 5 5 0
1 2 3 2 3 4 5 0
1 2 2 2 3 0
5 5 5 5 4 5 5 5 5 6 0
7 7 6 6 6 6 2 3 0
7 6 6 6 6 7 3 2 1 2 0
1 2 3 4 3 2 1 2 3 4 5 6 5 4 3 2 0
2 2 2 3 3 3 2 2 2 3 3 3 4 4 4 1 1 1 0
1 2 3 9 8 7 4 5 3 7 5 6 0
0
OUTPUT

Code: Select all

Nr values = 3:  2.000000 0.000000
Nr values = 3:  0.000000 2.000000
Nr values = 5:  2.000000 2.000000
Nr values = 5:  4.000000 0.000000
Nr values = 5:  0.000000 4.000000
Nr values = 7:  0.000000 6.000000
Nr values = 7:  1.000000 5.000000
Nr values = 4:  0.000000 0.000000
Nr values = 7:  2.500000 1.000000
Nr values = 5:  4.000000 0.000000
Nr values = 10:  5.000000 4.000000
Nr values = 8:  1.000000 6.000000
Nr values = 10:  1.000000 7.000000
Nr values = 16:  4.000000 3.500000
Nr values = 18:  5.500000 3.000000
Nr values = 12:  1.500000 1.666667
Hope it helps
keep it real!

this is your incorrect test case:
4 4 4 3 3 3 4 0
it should be
Nr values = 7: 1.000000 5.000000
but you have
Nr values = 7: 3.000000 5.000000

and here's more test cases for those who have difficulty solving it:

Hope it helps

7 6 6 6 6 7 3 2 1 2 0 -> Why is Nr values = 10: 1.000000 7.000000 ?

may be more correctly is 1.000000 3.500000 or not? please explain i have a problem with testing :o

413 - up and down sequences

Post by xintactox » Fri Aug 18, 2006 1:02 pm

Hello everybody!

I tried lots of stuff but I think I didn't understand the problem at all... I think I am doing the wrong thing when the sequences has neutral values (no up nor down)...

It works fine for lots of inputs, but I tried with this

Code: Select all


1 2 3 4 5 6 7 8 0
8 7 6 5 4 3 2 1 0
1 1 1 1 1 0
9 9  9 9 0
1 2 1 2 1 2 0
2 1 2 1 2 1 0
1 2 1 0
2 1 2 0
1 2 3 2 1 2 3 2 1 0
1 5 32 32 32 15 15 1 5 1 1 1 1 1 1 0
3 0
100 100 100 99 100 100 99 100 99 0
0
and it fails on the 10th and in the last cases, but i just cant understand why!!!

itś giving me

Code: Select all


Nr values = 8:  7.000000 0.000000
Nr values = 8:  0.000000 7.000000
Nr values = 5:  0.000000 0.000000
Nr values = 4:  0.000000 0.000000
Nr values = 6:  1.000000 1.000000
Nr values = 6:  1.000000 1.000000
Nr values = 3:  1.000000 1.000000
Nr values = 3:  1.000000 1.000000
Nr values = 9:  2.000000 2.000000
Nr values = 15:  5.500000 3.000000
Nr values = 1:  0.000000 0.000000
Nr values = 9:  1.000000 6.000000
but according with a post about the same problem here in the forum it should be

Code: Select all


Nr values = 8:  7.000000 0.000000
Nr values = 8:  0.000000 7.000000
Nr values = 5:  0.000000 0.000000
Nr values = 4:  0.000000 0.000000
Nr values = 6:  1.000000 1.000000
Nr values = 6:  1.000000 1.000000
Nr values = 3:  1.000000 1.000000
Nr values = 3:  1.000000 1.000000
Nr values = 9:  2.000000 2.000000
Nr values = 15:  2.500000 4.500000
Nr values = 1:  0.000000 0.000000
Nr values = 9:  1.500000 1.666667
My code is as follows:

Code: Select all


#include <stdio.h>

#define UP 1
#define DOWN 2
#define NEUTRAL 3
int main()
{
   int serie[31];
   int NEUTRALVALUE;
   int totalUP;
   int totalDOWN;
   int totalUPSequences, totalDOWNSequences;
   int INDEX;   
   int stateOLD, stateNEW;
   int size;
   bool flag = true;
   int firstDeviation = -1;
   
   while(flag)
   {      
      totalUP = 0;
      totalDOWN = 0;
      NEUTRALVALUE = 0;
      totalUPSequences = 0;
      totalDOWNSequences = 0;   
      stateOLD = -1;   //indefinido      
            
      //lendo a s
