875. 爱吃香蕉的珂珂 这题时间要求比较严格... 首先,将piles排序,然后二分查找. 总之,答案K肯定位于piles[?]piles[?+1]或者1piles[0]之间 所以我们先二分把?找到,然后再二分找到K即可 class Solution { public int minEatingSpeed(int[] piles, int H) { Arrays.sort(piles); if (H == piles.length) { return piles[piles.length -…

猴猴吃香蕉 背包DP \(D\)次询问,第\(i\)次询问,每次有\(n_i\)个带权香蕉,问有多少方案使香蕉之积为\(k_i\),对结果取模\(1000000007\) \(n\le 10^3,k\le 10^8,D\le 20\) 背包DP的变种. 设\(f[i][j]\)选完第\(i\)个物品时,乘积为\(j\)的方案数. 然后可以发现能组成\(k\)的数一定是\(k\)的约数,所以这个背包的体积就是\(k\)的约数这个集合,这样就可以避免碰\(k\)导致TLE了,这是本题最关键的一点.…
