Am facut o sursa C++, in care mergi de la 1 la radical(1000000000) adica 31622 + 1 si asfel poti obtine 100puncte. Succes!
#include <bits/stdc++.h>
using namespace std;
int ninv, i, a, b, nr, n, k, r;
int main()
{
cin >> a >> b;
for(i = 1; i <= 31623; i ++)
{
n = i * i;
k = n;
ninv = 0;
while(n)
{
ninv = ninv * 10 + n % 10;
n = n / 10;
}
r = sqrt(ninv);
if(r * r == ninv && k >= a && k <= b) nr++;
}
cout << nr;
return 0;
}
