leetcode 1011. 在 D 天内送达包裹的能力
作者:互联网
抽象为把序列分成D段,求和最大的段的最小值
下界为最大值,上界为序列和,二分结果,每次去验证是否合适即可
class Solution { public: int shipWithinDays(vector<int>& weights, int D) { int total = 0; int max_v = weights[0]; for(int i = 0; i < weights.size(); i++) max_v = max(max_v, weights[i]), total += weights[i]; int x = max_v, y = total; int cnt = 1, cnt_s; while(x < y) { cnt_s = 0; cnt = 1; int mid = (x + y) / 2; int i; for(i = 0; i < weights.size(); i++) if(cnt_s + weights[i] <= mid) cnt_s += weights[i]; else cnt_s = weights[i], cnt++; if(cnt > D) x = mid + 1; else y = mid; } return x; } };
