Hey Guys,

I was getting TLE for the above solution, can someone tell what was wrong?
Help would really be appreciated.

Thank You

A small correction, 0. and . themselves hold no meaning, as the question itself suggests that

After all the character replacements, the string is guaranteed to be a positive decimal number.

my all test cases are working properly and have checked each and every possibility of test case that can be possible but it is still showing wrong answer.
Here is my code. please someone go through it and help me out.

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

int main()
{
int t,n,i,j,a,k,e,d,flag,flag1,b;
char s[1000001],c[127],p[127],m[1000001];
scanf("%d",&t);
while(t--)
{
scanf("%d",&n);
for(i=0;i<n;i++)
{
scanf(" %c %c",&c[i],&p[i]);
}
scanf("%s",s);
flag=0;
flag1=2;
a=strlen(s);
if(n!=0)
{
for(i=0;i<a;i++)
{
for(j=0;j<n;j++)
if(s[i]==c[j])
{
s[i]=p[j];
break;
}
}
	}
for(i=0;i<=a;i++)
{ if(s[i]>'0' && flag==0)
{
flag=1;
j=i;
}
if(s[i-1]>'0' && s[i]=='0')
k=i-1;
else if(s[i-1]>'0' && s[i]=='\0')
k=i;
if(s[i]=='.' && flag==0)
{ flag1=0;
e=i;
}
if(s[i]=='.' && flag==1)
{ d=i;
flag1=1;
}
}
if(flag1==2)
{
for(i=j;i<a;i++)
m[i-j]=s[i];
}
else if(flag==1 && flag1==1)
{
if(k>d)
for(i=j;i<=k;i++)
m[i-j]=s[i];
else
for(i=j;i<d;i++)
m[i-j]=s[i];
}
else
{
for(i=e;i<=k;i++)
m[i-e]=s[i];
}
if(flag!=1)
printf("0\n");
else
printf("%s\n",m);
b=strlen(m);
for(i=0;i<b;i++)
m[i]='\0';
	for(i=0;i<n;i++)
c[i]='\0';
	for(i=0;i<n;i++)
p[i]='\0';
}

return 0;
}

Hi,

My solution is http://www.codechef.com/viewsolution/4079595.My solution passed all the testcases successfully. Can you please help me to find the error with my solution.

25

hi…I usually code in java…and I referred to the Editorialist’s solution for this problem. With all due respect, I think there is one case where the output’s not valid…

Input:

1

1

z .

343z.89

Output:
343…89

Well, is it or is it not a valid output ?

P.S. : No disrespect to anyone considering I’m just a newbie.
