    2070 - Most Beautiful Item for Each Query.

    Medium

    You are given a 2D integer array items where items[i] = [pricei, beautyi] denotes the price and beauty of an item respectively.

    You are also given a 0-indexed integer array queries. For each queries[j], you want to determine the maximum beauty of an item whose price is less than or equal to queries[j]. If no such item exists, then the answer to this query is 0.

    Return an array answer of the same length as queries where answer[j] is the answer to the jth query.

    Example 1:

    Input: items = [[1,2],[3,2],[2,4],[5,6],[3,5]], queries = [1,2,3,4,5,6]

    Output: [2,4,5,5,6,6]

    Explanation:

    • For queries[0]=1, [1,2] is the only item which has price <= 1. Hence, the answer for this query is 2.

    • For queries[1]=2, the items which can be considered are [1,2] and [2,4].

    The maximum beauty among them is 4.

    • For queries[2]=3 and queries[3]=4, the items which can be considered are [1,2], [3,2], [2,4], and [3,5].

    The maximum beauty among them is 5.

    • For queries[4]=5 and queries[5]=6, all items can be considered.

    Hence, the answer for them is the maximum beauty of all items, i.e., 6.

    Example 2:

    Input: items = [[1,2],[1,2],[1,3],[1,4]], queries = [1]

    Output: [4]

    Explanation:

    The price of every item is equal to 1, so we choose the item with the maximum beauty 4.

    Note that multiple items can have the same price and/or beauty.

    Example 3:

    Input: items = [[10,1000]], queries = [5]

    Output: [0]

    Explanation:

    No item has a price less than or equal to 5, so no item can be chosen.

    Hence, the answer to the query is 0.

    Constraints:

    • 1 <= items.length, queries.length <= 105
    • items[i].length == 2
    • 1 <= pricei, beautyi, queries[j] <= 109
