plz gimme a 5 digit test case where my logic fails
code removed after ACC. Thank you leppy once more :)
wat a blunder mistake :@ :@
14 days later
Hey guys,
I've tried out the test cases here (and they work fine for me), but I just can't seem to get AC. I've used forward DP. Any help?
#include<stdio.h>
#include<string.h>
int valid;
long long int dp[10000];
int count(char str[],int len)
{
memset(dp,0,sizeof(dp));
int i;dp[0]=1;
for(i=1;i<len;i++) {
//if(str[i]=='0')
dp[i]=dp[i-1];
//else
{ if(str[i-1]=='1')
{ if(dp[i-1]==1 && str[i]!='0')
dp[i]=2;
else if(str[i]!='0')
dp[i]=dp[i-1]+dp[i-2];
}
if(str[i-1]=='2' && (str[i]>='0' && str[i]<='6')) {
if(dp[i-1]==1 && str[i]!='0')
dp[i]=2;
else if(str[i]!='0')
dp[i]=dp[i-1]+dp[i-2];
}
}
}
/* for(i=0;i<len;i++)
printf("%d ",dp[i]);
printf("\n");
*/ return dp[len-1];
}
int main()
{
while(1) {
char str[5010];
scanf("%s",str);//cout<<str<<endl;
if(strcmp("0",str)==0)
return 0;
printf("%d\n",count(str,strlen(str)));
valid=0;
}
return 0;
}

works for all above mentioned test cases but is giving WA 
a is similar to dptable[i-2]
b is similar to dptable[i-1]
#include<stdio.h>
int main(void)
{
char str[5001];
unsigned long long int a,b,cnt=0,i=1,n;
scanf("%s",str);
while(str[0]!='0')
{
a=1;
b=1;
cnt=0;
i=1;
while(str[i]!='\0')
{
if(((str[i-1]=='2' && str[i]<'7') || (str[i-1]=='1')) && str[i]!='0')
cnt=a+b;
else if(str[i]=='0')
{
if(str[i-1]=='2' || str[i-1]=='1')
cnt=a;
else
{cnt=0; break;}
}
else
cnt=b;
a=b;
b=cnt;
i++;
}
printf("%llu\n",cnt);
scanf("%s",str);

Hi,
Could you pls explain how to consider the input like:
301
Isn't this an invalid test case? and hence o/p should be 0 ?
Well, I think that there will be no invalid case in the input data. Thus it doesn't matter what your code returns for this case. I got AC without considering invalid testcases.

My solution produces valid op for all the test cases mentioned here. However, it fails when i submit it. Any idea which test cases it could fail to?
#!/usr/bin/env python
def solution(a):
a = str(a)
poss = [0] * len(a)
for i in xrange(len(a)):
if i == 0:
poss[i] = 1
elif i > 0:
poss[i] = poss[i-1]
if int(a[i-1] + a[i]) < 27 and a[i] != '0':
if i >= 2:
poss[i] = poss[i-2] + poss[i-1]
else:
poss[i] = 2
return poss[-1]
while True:
a = int(raw_input())
if a == 0:
exit()
else:
print solution(a)3 months later
