我的码风合适吗??

#include <bits/stdc++.h>
using namespace std;
int c[200001], n, a, y, _index = 0;
int main() {
	cin>>n;
	for (int i = 1; i <= n; i ++) {
		cin >> a;
		if (a == 0) {
			cin >> y;
			_index ++;
			c[_index] = max(c[_index - 1],y);
		}
		if (a == 1) if (_index != 0) _index --;
		if (a == 2) cout << c[_index] << endl;
	}
	return 0;
}
