I've got the right output for the simple input, but the result of submission is WA.

Can you tell me what is your output with this input ?

Input:

Code: Select all

3
12 5
48 65 53 3 90 3 90 30 52 75 54 22
10 4
82 36 6 11 33 33 25 79 9 7
9 5
64 16 75 91 1 71 43 81 13
My WA output:

Code: Select all

48 65 / 53 3 90 / 3 90 30 / 52 75 / 54 22
82 / 36 6 11 / 33 33 25 / 79 9 7
64 / 16 75 / 91 1 / 71 43 / 81 13

I am getting correct result for all the test cases posted in this thread. Still I am getting WA at the judge. I used the binary search + greedy approach as discussed in this thread. Can someone figure out my mistake or post some more tricky cases?

Code: Select all

#include<iostream>
#include<vector>
#include<string>
#include<queue>
#include<sstream>
#include<map>
#include<stack>
#include<set>
#include<cmath>
#include<iomanip>
using namespace std;
#define PB push_back
#define vi vector<int>
#define LL long long
#define all(v) v.begin(),v.end()
#define GI ({int t ; scanf("%d",&t);t;})

int M,K;
int A[500];
bool go(LL maxsum)
{
	LL sum=0;
	int k=1;
	for(int i=0;i<M;i++)
	{
		if(sum+A[i]>maxsum){
			sum=A[i];
			k++;
		}
		else
			sum+=A[i];
	}
	return (sum<=maxsum && k<=K);
}
void print(LL maxsum)
{
	int k=1;
	vi res;
	res.PB(A[M-1]);
	LL sum=A[M-1];
	for(int i=M-2;i>=0;i--)
	{
		if(sum+A[i]>maxsum){
			res.PB(-1);
			res.PB(A[i]);
			sum=A[i];
			k++;
		}
		else{
			res.PB(A[i]);
			sum+=A[i];
		}	
	}
	reverse(all(res));
	

	while(k<K)
	{
		for(int i=1;i<res.size();i++)
			if(res[i-1]!=-1 && res[i]!=-1){
				res.insert(res.begin()+i,-1);
				k++;
				break;
			}	
	}

	printf("%d",res[0]);
	for(int i=1;i<res.size();i++)
	{
		if(res[i]==-1)
			printf(" /");
		else
			printf(" %d",res[i]);
	}
	printf("\n");		
}
int main()
{
	int t=GI;
	while(t--)
	{
		M=GI; K=GI;
		for(int i=0;i<M;i++) A[i]=GI;
		
		LL lo=0,hi=1LL<<40;
		for(int i=0;i<50;i++)
		{
			LL mid=(lo+hi)/2;
			if(go(mid))
				hi=mid;
			else
				lo=mid;
		}
		print(hi);
	}
}

my method is binary serch

i thought i have trouble on mark the splash character

(the bool array anw[10000] : if anw ==true means that is should print '/' before x)

thx=)

Code: Select all

#include<iostream>

using namespace std;

int N,m,k;
int x[10000];
int L,H,M;
bool anw[10000];
bool check(int a)
{
     int tmp=0,q=1;
     for(int i=m;i>=1;i--)
     {
          tmp=tmp+x[i];
          if(tmp>a)
          {
               q++;
               tmp=x[i];
          }
     }
     if(q<k)return true;
     else   return false;
     
}

main()
{     
     while(cin>>N)
     {
          while(N--)

Got AC.

There is a problem just like this in the topcoder tutorial of Binary Search.Interested readers can read it : http://community.topcoder.com/tc?module ... narySearch
Accept who you are :)

Hi all,
I get a time limit exceded when I run my code. Can someone please suggest some ways to optimize my code.I had used binary search to get the maximum number of pages. Thanks in advance!

Code: Select all

package s43;

import java.util.LinkedList;
import java.util.Scanner;




public class Main {
	
	static int m,k,left,right,mid;
	static LinkedList<Integer> p;
	
	public static int getsum(int a, int b)
	{
		int sum=0;
		for(int i=a;i<=b;i++)
		{
			sum+=p.get(i);
		}
		return sum;
	}
	
	public static int binarySearch(int left, int right)
	{
		int mid;
		int count=1; int sum=0;
		if(left<right)
		{
		mid=(left+right)/2;
		for(int i=m-1;i>=0;i--)
		{
			if((sum+p.get(i))<=mid)
				sum=sum+p.get(i);
			else
			{
				count++;
				i++;
				sum=0;
				if(count>k)
					break;
				
			}
		}
		
		if(count==k)
		{
			int mid1 = binarySearch(left,mid);
			if(mid1<mid)
				return mid1;
			else
				return mid;
						
			
		}
		else
		{
			if(count<k)
				return binarySearch(left,mid);
			else
				return binarySearch(mid+1,right);
		}
		}
		else
			return left;
				
	}



	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner inp = new Scanner(System.in);
		 p=new LinkedList<Integer>();
	
		int num=inp.nextInt();
		String str="";
		for(int l=0;l<num;l++)
		{
		m = inp.nextInt();
		k = inp.nextInt();
		for(int i=0; i<m; i++)
			p.add(inp.nextInt());
		left=1;  
		right=getsum(0,m-1);
		int maxi = binarySearch(left,right);
		LinkedList<String> finl = new LinkedList<String>();
		
		int sum=0;int count=1;
		for(int i=m-1;i>=0;i--)
		{
			if((sum+p.get(i))<=maxi)
			{
				sum=sum+p.get(i);
				finl.add(Integer.toString(p.get(i)));
			}
			else
			{
				count++;
				i++;
				sum=0;
				if(count>k)
					break;
				finl.add("/");
			}
		}
		
		if(count==k)
		{
		 for(int i=(finl.size()-1); i>=0; i--)
		 {
			str+=(finl.get(i) + " ");
		 }
		 str+="\n";
		 finl.clear();
		}
		else
		{
			finl.clear();
			sum=0;count=1;
			for(int j=m-1;j>=0;j--)
			{
				if((sum+p.get(j))<=maxi)
				{
					sum=sum+p.get(j);
					finl.add(Integer.toString(p.get(j)));
				}
				else
				{
					count++;
					
					sum=0;
					finl.add("/");
					k--;
					m=j+1;
					maxi=binarySearch(1,getsum(0,j));
					int pi=getsum(0,j);
					int si=k;
					j++;
					}
			}
			 for(int i=(finl.size()-1); i>=0; i--)
			 {
				 str+=(finl.get(i) + " ");
			 }
			 str+=("\n");
			 finl.clear();
			
		}
		
		
	finl.clear();
	p.clear();

	}
		System.out.println(str);
	}

Don't use a package.
Try using BufferedReader and BufferedWriter.

Just found one bug in my code.
If you solve this problem using DP technique, you have to pay attention to data type.
There may be 5,000,000,000 pages at most, which exceeds INT_MAX.
(Therefore, initializing to INT_MAX is not big enough.)
Life shouldn't be null.
