Hi.
Somebody can say me why this example is MISMATCH?
My Output: MATCH
Output Udebug: MISMATCH
I think that the first line could be the number 9(YYYYNYY) and the second line could be the number 8(YYYYYYY)
Thanks in advance and sorry my poor english.

No segments will ever fail into the ON mode; no burned out segments will recover.
If YYNNNNY is 9(YYYYNYY) then segments c, d, and f are burned out.
If YYNYNYN is 8(YYYYYYY) it's a MISMATCH because segments d and f are now on.

checked my output with Udebug.....
tried all the possible inputs and outputs....
everything is right although UVA is giving WA....
will u plz check my code?
Code: Select all
#include<bits/stdc++.h>
using namespace std;
int led[]={126,48,109,121,51,91,95,112,127,123};
bool chk[10],flag=false;
int main()
{
int Count=0;
//freopen("arf.txt","r",stdin);
int n,data[12];
char ch,temp = 127;
while(1){
memset(data,0,sizeof(data));
flag=false;
scanf("%d",&n);
if(n<1||n>10)
break;
for( int i=1;i<=n;i++)
{
for(int j=6;j>=0;j--)
{
scanf(" %c",&ch);
if(ch=='Y')
data[i] = data[i]|1<<j;
}
// printf("%d\n",data[i]);
}
for (int i=0;i<=9;i++)
{
if((data[1]&led[i])==data[1])
chk[i] = true;
}
for(int i=0;i<=9&&!flag;i++)
{
temp =0;
if(chk[i])
{
chk[i]=false;
for(int j=1;j<=n;j++)
{
//if(data[j]!=0)
temp = temp |(((127&led[i-j+1]))^data[j]);
if((data[j]&led[i-j+1])==data[j]&&!(data[j] & temp))
{
if(j==n)
flag = true;
continue;
}
else break;
}
}
}
if(flag)
printf("MATCH\n");
else
printf("MISMATCH\n");
}
return 0;
}

The test data on uDebug end with end of line instead of 0, beware of it.
