pile

Koko loves to eat bananas. There are N piles of bananas, the i -th pile has piles[i] bananas. The guards have gone and will come back in H hours. Koko can decide her bananas-per-hour eating speed of K . Each hour, she chooses some pile of bananas, and eats K bananas from that pile. If the pile has less than K bananas, she eats all of them instead, and won't eat any more bananas during this hour. Koko likes to eat slowly, but still wants to finish eating all the bananas before the guards come back. Return the minimum integer K such that she can eat all the bananas within H hours. Example 1:

题面 Description There are \(k\) piles of stones in a circle, numbered from \(0\) to \(k - 1\) , where the number of the stones in each pile is \(n\) initially. You can do some round operations, where the initial round is numbered as the \(1\) -st round. The operation of the \(i\) -th round is to modify the pile of stones numbered \((i - 1) \bmod k\) . In each round, you should remove from this pile some stones (at least one stone), satisfying that the number of stones in this pile before this operation is a multiple of the number of stones in this pile after operation, which means that you

Then he may have shuffled the letters and put them in one pile in front of the door. The next morning it was

A move consists of merging exactly K consecutive piles into one pile, and the cost of this move is equal to the total number of stones in these K piles. Find the minimum cost to merge all piles of stones into one pile. If it is impossible, return -1 . Example 1: Input: stones = [3,2,4,1], K = 2 Output: 20 Explanation: We start with [3, 2, 4, 1]. We merge [3, 2] for a cost of 5, and we are left with [5, 4, 1]. We merge [4, 1] for a cost of

Alice and Bob have received three big piles of candies as a gift. Now they want to divide these candies as fair as possible. To do this, Alice takes one pile of candies, then Bob takes one of the other two piles. The last pile is split between Alice and Bob as they want: for example, it is possible that Alice takes the whole pile, and Bob gets nothing from it. After taking the candies from the piles, if Alice has more candies than Bob, she discards some candies so that the number of candies she has is equal to the number of candies Bob has. Of course, Bob does the same if he has more candies.
