#include<cstdio>
#include<iostream>
using namespace std;
int a[1000000];
int main()
{
	int n, m, sum = 0, count = 1;
	cin >> n >> m;
	for (int i = 0; i < n; i++)
		{
			cin >> a[i];
			sum += a[i];
			if (sum >= m)
				{
					if (sum == m)
						{
							sum = 0;
						}
					else
						{
							sum = 0;
							sum += a[i];
						}
					count++;
				}
		}
	cout << count << endl;
	return 0;
}

样例都过不了，却能ac 这啥情况 还有我代码错哪了
