Link to the problem:
I don’t know in which case its failing.
Below is my code:
#include<iostream>
#include<cstdio>
#include<cstring>
#define FAST_IO ios_base::sync_with_stdio(false);cin.tie(NULL);
using namespace std;
int main()
{
FAST_IO
int N,Q;
cin>>N>>Q;
char file_extension[N][11],media_type[N][51],name_of_file[Q][51];
for(int i=0;i<N;i++)
cin>>file_extension[i]>>media_type[i];
for(int i=0;i<Q;i++)
{
cin>>name_of_file[i];
int len=strlen(name_of_file[i]),flag=0,dot_pos;
for(int j=len-1;j>=0;j--)
{
if(name_of_file[i][j]=='.')
{
flag=1;
dot_pos=j;
break;
}
}
if(flag==1)
{
int flag_1=0;
for(int k=0;k<N;k++)
{
int val=dot_pos+1,len_1=strlen(file_extension[k]),count=0;
for(int k1=0;k1<len_1;k1++)
{
if(file_extension[k][k1]==name_of_file[i][val])
{
count++;
val++;
}
else
break;
}
if(len_1==count)
{
flag_1=1;
cout<<media_type[k]<<"\n";
break;
}
}
if(flag_1==0)
cout<<"unknown"<<"\n";
}
else
{
cout<<"unknown"<<"\n";
}
}
return 0;
}
