这道题怎么求解？

#include<iostream> (30316)#include<vector> #include<bits/stdc++.h> using namespace std; // 求能量为e时，机器人需要几小时搬运 int sum(vector<int>&amp; bricks,int e){ int rst = 0; for(int i=0;i<bricks.size();i++){ rst += ceil(float(bricks[i])/ e ); } return rst; } int main(){ vector<int> bricks; int num; while(cin >> num ){ bricks.push_back(num); char ch = getchar(); if(ch == '\n') break; } if(bricks.size() > 8) cout << -1 << endl; int ans; sort(bricks.begin(),bricks.end()); int mid ,l = 0,r = bricks[bricks.size() - 1]; while(l < r){ mid = (l + r) / 2; if(sum(bricks,mid) > 8) l = mid + 1; else r = mid; } if(sum(bricks,l) > 8) ans = -1; else ans = l; cout << ans << endl; return 0; }

import math def min_e(b, H): l, r = 1, max(b) while l < r: m = (l + r) // 2 if sum(math.ceil(i/m) for i in b) > H: l = m + 1 else: r = m if sum(math.ceil(i/l) for i in b) > H: return -1 return l b = list(map(int, input().split())) print(min_e(b,8))

我也遇到了这个题。等待大神解答
