Discuss: this is simple list implementation problem.if you know list then you can it without any trouble. just input the line in a string and then if '[' in string then change the iterator of string in begin and if you found ']' then change the iterator of string in end. and else just insert the element in the list.
try your self before see the code
#include<bits/stdc++.h>
using namespace std;
int main()
{
int n,i,j,cnt=0,flag=0;
char str[100001];
while(cin >>str)
{
list<char> lst;
if(!strcmp(str,"-1"))
break;
list<char>::iterator p=lst.begin();
int b=0,e=0;
n=strlen(str);
for(i=0;i<n;i++)
{
if(str[i]=='[')
{
p=lst.begin();
}
else if(str[i]==']')
{
p=lst.end();
}
else
lst.insert(p,str[i]);
}
p=lst.begin();
while(p!=lst.end())
{
cout <<*p;
p++;
}
cout <<endl;
}
return 0;
}
