Before post anything u must read the previous posts carefully.... 

i think i read them carefully. Or if i overlooked something, can u tell me the matter for which i m getting WA?

p.s. i use char & modify the char value by adding 128 before using it as a array index. I think u already saw it.

Post by mukit » Wed Nov 21, 2007 10:30 am

int main()
{
	int test;
	int nc;
	unsigned char ch;
	float sum=0.0;
	char str[MAX];
	long int x,j,i;
	float val[MAX]={0};
	long int nl;
	int p;
	cin>>test;
	for(i=0;i<test;i++)
	{
		cin>>nc;
		for(x=0;x<nc;x++)
		{
			cin>>ch>>val[int(ch)+256];
		}
		cin>>nl;
		while(1)
		{ 
			if(nl<0)break;
			gets(str);
			for(p=0;p<strlen(str);p++)
			{
				sum+=val[(int(str[p])+256)];
			}
			nl--;
		}
		cout<<sum/100.00<<"$"<<endl;
		sum = 0.0;
	}
	return 0;

Hi ;), I take careful about the unsigned char, and i had been careful about the char '\n' , '\t', ' ', ...... but i got WA. Here is my code... thanks for your help.

Code: Select all

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

using namespace std;

int costos[300];
int total;

int main(){
	int casos;
	cin >> casos;
	for (int caso=0; caso< casos; caso++){
		total=0;
		for (int h=0; h<300 ; h++) costos[h]=0;
		int k;
		cin >> k;
		unsigned char tempca;
		int tempco;
		for (int kk=0 ; kk<k ; kk++){
			getchar();
			tempca=getchar();
			cin >> tempco;
			costos[tempca]=tempco;
		}
		int lineas;
		cin >> lineas;
		string frase;
		getline(cin , frase);
		for (int linea=0;linea<lineas; linea++){
			getline(cin , frase);
			for (int o=0;o<frase.size() ; o++){
				total+=costos[frase[o]];
			}
		}
		double tempooo=total/100.0;
		printf("%.2f$\n" , tempooo);
	}
	return 0;
}

I am not getting one thing.This problem is simply trivial problem.no trick, no special input.just do what they want.It will be AC.
I used char not unsigned char(in c++)
I dont feel headache with type of char positive or negetive.

It is one of the problems that can be AC in first submission.
one thing thing carefully about the output format.(one leading 0,not 2,so 4.00 is invalid);

hope it will help those who r still confused with what to do.

int val[300] ;
int c[300] ;
char s[10010] ;

int main()
{
	int n , t , i , x ;
	long long int res ;
	char ch ;

//	freopen("c:\\1.txt" , "r" , stdin) ;

	scanf("%d\n" , &t) ;
	while(t-- > 0)
	{
		scanf("%d" , &n) ;
		gets(s) ;
		memset(val , 0 , sizeof(val)) ;
		memset(c , 0 , sizeof(c)) ;
		while(n-- > 0)
		{
			ch = getchar() ;
			scanf("%d" , &x) ;
			gets(s) ;
			val[ch + 128] = x ;
		}

		scanf("%d" , &n) ;
		gets(s) ;
		while(n-- > 0)
		{
			gets(s) ;
			for(i = strlen(s) - 1 ; i >= 0 ; i--)
				c[s[i] + 128]++ ;
		}

		for(i = 0 , res = 0 ; i < 300 ; i++)
			res += (long long int)val[i] * c[i] ;

		printf("%.2llf$\n" , (double)res / 100) ;
	}

try to solve the problem with long(even no need long long)
The only thing u have to do is finding modulous by 100 in each step.
after calculating dollars and its scents then print
b careful about printing format after decimal point...
hope it helps.
if u r still not clear I will explain u more.

I am not agree with kbr_iut.....
Output of above input will be 1.00$(may be 1.0$ also correct).
No need to use long long.
My output section which give me AC.

Code: Select all

cout<<res/100<<".";
printf("%02d$\n",res%100);
NB: I handled unsigned char.

yes u r right. both of them are correct. I just did it according to the problem statement.
and u r also right about the datatype .int or long is enough to get AC.
thanx for the correction.

					if(a[j]==c[k][l])
						p++;
			}
			printf("%c %ld\n",a[j],p);
			sum=sum+(p*b[j]);
