#include <bits/stdc++.h>
#define el '\n'
typedef long long ll;
typedef long double ld;
#define Beevo ios_base::sync_with_stdio(0); cin.tie(0); cout.tie(0);
using namespace std;
void testCase() {
ll a, b;
cin >> a >> b;
int cnt = 0;
for (int i = 1; 1LL * i * i <= b; i++) {
if (1LL * i * i < a)
continue;
string s = to_string(1LL * i * i);
reverse(s.begin(), s.end());
if (s[0] == '0')
continue;
int sq = sqrt(stoll(s));
cnt += 1LL * sq * sq == stoll(s);
}
cout << cnt;
}
signed main() {
Beevo
int t = 1;
// cin >> t;
while (t--)
testCase();
return 0;
}
这程序好像有点Bug,我给组数据试试?
