我认为我是最简单的那个

#include"iostream"
using namespace std;
int main() {

string a;
string b;

getline(cin, a);
getline(cin, b);

b = " " + b + " ";

for (int i = 0 ; i < a.size(); i++) {
	if (a[i] >= 'A' && a[i] <= 'Z') {
		a[i] = a[i] + 32;
	}
}

for (int i = 0 ; i < b.size(); i++) {
	if (b[i] >= 'A' && b[i] <= 'Z') {
		b[i] = b[i] + 32;
	}
}

int s = 0;
int w = -1;
bool f = false;

for (int i = 0; i < b.size() - a.size(); i++) {
	if (b.substr(i, a.size()) == a && b[i - 1] == ' ' && b[i +a.size() ] == ' ') {
		if (!f) {
			w = i;
			f = true;
		}
		s++;
	}
}

if (s == 0) {
	cout << -1;
} else {
	cout << s << " " << w - 1;
}

return 0;

}
