您的答案為: -2 正確答案為: 0
不太懂 為什麼其他測資都是正確的
只有這個測資錯?
這是我的程式碼
#include <iostream>
#include <vector>
#include <string>
#include <sstream>
using namespace std;
int main () {
int N;
while (cin >> N) {
vector<int> list;
int t;
for (int i=0; i<N; i++) {
cin >> t;
list.push_back(t);
}
int best = -100;
for (int i=1; i<=N; i++) {
int sum = 0;
auto it = list.begin();
while (it != list.begin()+i) {
sum += *it;
it++;
}
if (sum > best) best = sum;
while (it != list.end()) {
sum += *it;
sum -= *(it-i);
if (sum > best) best = sum;
it++;
}
}
cout << best << endl;
}
return 0;
}
int best = 0
