10684 - The jackpot

[mamun]

Declare check[][] and money[] globally or as static in main().

[helloneo]

the array check[][] is too big..~

[Obaida]

Is there any reason to have CE...! This is crazy....
Any one could debug my program and suggest me that it's ok or not...

Code: Select all

Thank you mf I was wrong in thinking..
AC.... :wink: 

[Obaida]

Ok... I traced why CE... I was using i in both loop... But now it is getting WA.... Help me...[/code]

Code: Select all

he can identify patterns of consecutive wins and elaborate a win-win strategy.
A bet is an amount of money and is either winning (and this is recorded as a positive value). 

i am not understand this two line of code. what do u mean by win win strategy.

well this is how my code looks like if i have found it to be coorect its the maximum sum and used dp for it can any one plz tell my errors or provide me with test case which would help me realize my error

long long i,j,arr[1001];
while(cin>>n && n!=0)
{
long long s[1001] = {0};
FOR(i,1,n+1)
cin>>arr;
s[0] = 0;
FOR(i,1,n+1)
s = MAX(s[i-1]+arr,arr);
if(s[i-1]>0)
cout<<"The maximum winning streak is "<<s[i-1]<<"."<<endl;
else
cout<<"Losing streak."<<endl;
}
** MAX & FOR are simple macros that i have used

[mathgirl]

Is this problem maximum consecutive sum or maximum sum ? I have tried both, but getting WA.

For example,
5 5 -1 5 5
Is the answer 10 or 19 ?

Code: Select all

#include<stdio.h>
#include<vector>

using namespace std;

int main()
{
	int n,re;
	re = scanf("%d",&n);
	while(n)
	{
		vector<int> input;
		int a;
		for(int j=1;j<=n;j++)
		{
			scanf("%ld",&a);
			input.push_back(a);
		}

		int sum = 0,maxs = 0;
		int i = 0,j;
		while(i<input.size())
		{
			sum = 0;
			j = i;
			while(j<input.size())
			{
				sum = sum + input[j];
				j++;
				maxs = max(sum,maxs);
			}
			i++;
		}

		if(maxs>0)
			printf("The maximum winning streak is %d.\n",maxs);
		else
			printf("Losing streak.\n");

		re = scanf("%d",&n);
		
	}

	return 0;
}

maximum possible gain out of a sequence of consecutive bets.

19.

Use %d when reading an int in scanf.

Why WA, where am I wrong?

Code: Select all

#include <stdio.h>
#include <iostream>
#include <iterator>
using namespace std;
int main()
{
    int n;
    while(scanf("%d",&n)&&n!=0){
    std::istream_iterator<int> int_it(cin),end;
    int sum=*int_it++;
    for(int i=2;i<n;++i)
    {
        sum+=*int_it++;
        if(sum<0)
        sum=0;
    }
    sum+=*int_it;
    if(sum>0)
    printf("The maximum winning streak is %d.\n",sum);
    else
    printf("Losing streak.\n");
    }

}

Try input:

0

Hi,

today I made this problem and I found something interesting.

I sent my code and while it was in queue I realized that my code failed for this case:

1
1
0

So I sent it again, but with the correction.

The funny thing is that when I checked I had the two submissions accepted.

The firstone's output was:

Losing streak.

and the second's:

The maximum winning streak is 1.

How could be this possible?

[brianfry713]

The second is correct. The judge can't test all possible inputs, so whatever was wrong with your code isn't tested by the judge's I/O.

try this
input:

5
12 -4
-3 4
9
0

output:

The maximum winning streak is 18.

I got TLE with this code but when I tried n=10000 it work faster than 3s.
Please help me improve my code.

Code: Select all

#include<stdio.h>
#include<algorithm>
using namespace std;
int main()
{
	int sum,n[10005],tmp[10005],big;
	while(1)
		{
		scanf("%d",&sum);
		if(sum==0)
		break;
		for(int i=0;i<sum;i++)
		{
			scanf("%d",&n[i]);
			tmp[i]=n[i];
		}
		big=*max_element(n,n+sum);
		for(int i=1;i<sum;i++)
		{
			for(int j=0;j<sum-i;j++)
			{
				tmp[j]+=n[j+i];
				if(big<tmp[j])
				big=tmp[j];
			}
			
		}
		if(big<1)
			printf("Losing streak.\n");
		else
			printf("The maximum winning streak is %d.\n",big);
	}
}
