You are given a (0-indexed) array of positive integers candiesCount
where candiesCount[i]
represents the number of candies of the ith
type you have. You are also given a 2D array queries
where queries[i] = [favoriteTypei, favoriteDayi, dailyCapi]
.
You play a game with the following rules:
\n\n0
.i
unless you have eaten all candies of type i - 1
.Construct a boolean array answer
such that answer.length == queries.length
and answer[i]
is true
if you can eat a candy of type favoriteTypei
on day favoriteDayi
without eating more than dailyCapi
candies on any day, and false
otherwise. Note that you can eat different types of candy on the same day, provided that you follow rule 2.
Return the constructed array answer
.
\n
Example 1:
\n\n\nInput: candiesCount = [7,4,5,3,8], queries = [[0,2,2],[4,2,4],[2,13,1000000000]]\nOutput: [true,false,true]\nExplanation:\n1- If you eat 2 candies (type 0) on day 0 and 2 candies (type 0) on day 1, you will eat a candy of type 0 on day 2.\n2- You can eat at most 4 candies each day.\n If you eat 4 candies every day, you will eat 4 candies (type 0) on day 0 and 4 candies (type 0 and type 1) on day 1.\n On day 2, you can only eat 4 candies (type 1 and type 2), so you cannot eat a candy of type 4 on day 2.\n3- If you eat 1 candy each day, you will eat a candy of type 2 on day 13.\n\n\n
Example 2:
\n\n\nInput: candiesCount = [5,2,6,4,1], queries = [[3,1,2],[4,10,3],[3,10,100],[4,100,30],[1,3,1]]\nOutput: [false,true,true,false,false]\n\n\n
\n
Constraints:
\n\n1 <= candiesCount.length <= 105
1 <= candiesCount[i] <= 105
1 <= queries.length <= 105
queries[i].length == 3
0 <= favoriteTypei < candiesCount.length
0 <= favoriteDayi <= 109
1 <= dailyCapi <= 109
给你一个下标从 0 开始的正整数数组 candiesCount
,其中 candiesCount[i]
表示你拥有的第 i
类糖果的数目。同时给你一个二维数组 queries
,其中 queries[i] = [favoriteTypei, favoriteDayi, dailyCapi]
。
你按照如下规则进行一场游戏:
\n\n0
天开始吃糖果。i - 1
类糖果之前,不能 吃任何一颗第 i
类糖果。请你构建一个布尔型数组 answer
,用以给出 queries
中每一项的对应答案。此数组满足:
answer.length == queries.length
。answer[i]
是 queries[i]
的答案。answer[i]
为 true
的条件是:在每天吃 不超过 dailyCapi
颗糖果的前提下,你可以在第 favoriteDayi
天吃到第 favoriteTypei
类糖果;否则 answer[i]
为 false
。注意,只要满足上面 3 条规则中的第二条规则,你就可以在同一天吃不同类型的糖果。
\n\n请你返回得到的数组 answer
。
\n\n
示例 1:
\n\n\n输入:candiesCount = [7,4,5,3,8], queries = [[0,2,2],[4,2,4],[2,13,1000000000]]\n输出:[true,false,true]\n提示:\n1- 在第 0 天吃 2 颗糖果(类型 0),第 1 天吃 2 颗糖果(类型 0),第 2 天你可以吃到类型 0 的糖果。\n2- 每天你最多吃 4 颗糖果。即使第 0 天吃 4 颗糖果(类型 0),第 1 天吃 4 颗糖果(类型 0 和类型 1),你也没办法在第 2 天吃到类型 4 的糖果。换言之,你没法在每天吃 4 颗糖果的限制下在第 2 天吃到第 4 类糖果。\n3- 如果你每天吃 1 颗糖果,你可以在第 13 天吃到类型 2 的糖果。\n\n\n
示例 2:
\n\n\n输入:candiesCount = [5,2,6,4,1], queries = [[3,1,2],[4,10,3],[3,10,100],[4,100,30],[1,3,1]]\n输出:[false,true,true,false,false]\n\n\n

1 <= queries.length <= 105
queries[i].length == 3
0 <= favoriteTypei < candiesCount.length
