Every time i send these problem i got WA i don't why 
this is code
#include <iostream>
#include <vector>
#include <cmath>
#include <algorithm>
#include <string>
#include <sstream>
using namespace std ;
bool isPlaindroom(string word)
{
for ( int i = 0; i < (word.length()/2); i++)
if (word[i] != word[(word.length()-1)-i])
return false;
return true;
}
string convertInt(long int number)
{
stringstream ss;//create a stringstream
ss << number;//add number to the stream
return ss.str();//return a string with the contents of the stream
}
int GetNextpalindrome(long int Start)
{
while (true)
{
Start = ++Start;
if (isPlaindroom(convertInt(Start)))
break;
}
return Start;
}
int main()
{
int x;
cin>>x;
long int m;
vector<int>v;
for (int i = 0 ; i < x ; i ++)
{
cin>>m;
v.push_back(GetNextpalindrome(m));
}
for (int i =0 ; i < v.size(); i ++)
{
cout<<v[i]<<endl;
}
return 0;
}
Please help
