i have changed a bit the initialization part but still WA

Please do not open a new topic for posts concerning the same problem.

And you have completely mistaken my previous reply... By initialization I mean setting the elements of your array count_a to 0. Check that statement, and hope you can get that fixed.

P.S. Remember to remove your code after you get AC.

I don't understand what did you want to mean. plz describe it by pointing the specific line. thank you very much.

HI,

Getting WA for this code

[code]
/*
Name: Hartals
Number: 10050
Type : ad hoc
Process : ON
Author :Salman Zaman
Email : zamansalman@gmail.com
Date : 02/06/05 01:27

*/

#include<stdio.h>
//#include<string.h>

//#include<conio.h>

int main(){

int n,p,t;
int days[4000];
int party[500];
int i,j,k,x,count;

//freopen("10050.txt","r",stdin);

scanf("%d",&t);
for(i=0;i<t;i++){
scanf("%d%d",&n,&p);
for(k=0;k<=n;k++)days[k]=0;
for(j=0;j<p;j++){
scanf("%d",&x);
for(k=x;k<=n;k=k+x){
days[k]=1;
}
}
for(k=7;k<=n;k+=7){
days[k]=0;
days[k-1]=0;
}
for(k=1,count=0;k<=n;k++){
if(days[k])count++;
}
printf("%d\n",count);

}

// getch();
return 0;
}
[/code]

Test case is ok but i think the problem is with weekends checking!!!

J & Jewel,

I'm affraid your input is slightly wrong
( does dot match the input description from
the problem statement ).

Here are your test cases corrected plus
one more test case.

INPUT

Code: Select all

OUTPUT

Code: Select all

I hope the test cases will be helpful to
Salman and/or to someone else.

Sorry salman and thanks to sadefcho ...may be 4 copy paste problem happends....

I don't know what make my program runtime error.
Actually, when I tested my program, it was no problem.
Who can advise me?

Code: Select all

#include <iostream>
#include <cstring>
using namespace std;
const int MAXPARTY = 110;
const int MAXDAY = 3700;
const int SAT = 7;

int main()
{
	int tscase;
	cin >> tscase;
	int days, partis;
	bool day[MAXDAY] = {false,};
	int party[MAXPARTY] = {0,};
	for(int i=0; i < tscase; i++)
	{
		// Input
		cin >> days >> partis;		
		for(int j=0; j < partis; j++)
		{
			cin >> party[j];
		}
		// Processing
		for(int k=1; k <= days; k++)
		{
			for(int m=0; m < partis; m++)
			{
				if( (k % party[m]) == 0 ) {
					day[k] = true;					
				}
			}
		}
		int count = 0;
		for(int k=1; k <= days; k++)
		{
			if( (day[k] == true) ) {
				if( (k % SAT) != 0 && (k % SAT) != 6) {
					count++;
				}
			}
		}
		// Output
		if( i == tscase-1 )
			cout << count;
		else
			cout << count << endl;

		// Clear 
		memset(day, 0x00, sizeof(int)*days);
		memset(party, 0x00, sizeof(int)*partis);
	}

	return 0;
}

I got A.C.
But, I have just changed my Clear part.
I used for-loop to clear array instead of memset function.
I can't understand why the memset function occur Runtime error.
Who can explain me about it?

You define 'day' as an array of bools yet you use sizeof(int) instead of sizeof(bool) when you specify the size of the array in memset. 'bool' is defined as a char so you are clearing data after the end of your array.

Oh, my GOD...
Thanks, kruptolus.
I'm really appreciate you.

thank you to help me.

both of c and c++ compiler told me runtime error.
but why?

array[1000] -> array[3651]
day[3651] -> day[100]

After getting correct answer, please delete above your code.

Best regards.

I have tried my program with all the sample input from the four threads on Hartals and it works perfectly for all of them. What am I missing? Thanks in advance.

Code: Select all

Figured out my problem.

10050 still WA?
