Count Numbers in Range Queries
MediumP3Coding
Given an array nums and a list of queries, where each query is [l, r], return for each query how many elements of nums have a value v with l <= v <= r. The array is not sorted and l <= r always holds.
Answer the queries in the same order they were given.
Example 1
- Input
- nums = [5,1,9,3,3], queries = [[1,3],[4,8],[10,20]]
- Output
- [3,1,0]
Example 2
- Input
- nums = [2,2,2], queries = [[2,2]]
- Output
- [3]
Example 3
- Input
- nums = [], queries = [[0,5]]
- Output
- [0]
Constraints
- 0 <= nums.length <= 10^5
- 1 <= queries.length <= 10^5
- -10^9 <= nums[i], l, r <= 10^9
