Count Subarrays With Fixed Bounds
You are given an integer array nums and two integers minK and maxK.
A fixed-bound subarray of nums is a subarray that satisfies the following conditions:
- The minimum value in the subarray is equal to
minK. - The maximum value in the subarray is equal to
maxK.
Return the number of fixed-bound subarrays.
A subarray is a contiguous part of an array.
Example 1
Input
nums = [1,3,5,2,7,5], minK = 1, maxK = 5Output
2The fixed-bound subarrays are [1,3,5] and [1,3,5,2].
Example 2
Input
nums = [1,1,1,1], minK = 1, maxK = 1Output
10Every subarray of nums is a fixed-bound subarray, so there are 10 possible subarrays.
Constraints
- 2 <= nums.length <= 10^5
- 1 <= nums[i], minK, maxK <= 10^6
