I was being interviewed 4 hours ago and here it is.
Given an array A, that is a permutation of n numbers [1-n]. Find the number of subarrays S that meets the following condition max(S) - min(S) = length(S) - 1.
Example 1:
Input: [4, 3, 1, 2, 5]
Output: 10
Explanation: subarrays that meet the condition are
[4]
[3]
[1]
[2]
[5]
[4 3]
[1 2]
[3 1 2]
[4 3 1 2]
[4 3 1 2 5]
There are 10 subarrays that meet the condition, so the answer should be 10.
