太难了。。。

#include <iostream> 
#include <vector>
using namespace std;
int minSegments(int n, int m, vector<int>& nums) { 
    int segments = 0; 
    int sum = 0;
for (int i = 0; i < n; i++) {
    sum += nums[i];
    if (sum > m) {
        segments++;
        sum = nums[i];
    }
}
if (sum > 0) {
    segments++;
}
return segments;
}
int main() { int n, m; cin >> n >> m;
vector<int> nums(n);
for (int i = 0; i < n; i++) {
    cin >> nums[i];
}
int result = minSegments(n, m, nums);
cout << result << endl;
return 0;
}
