[Leetcode 962] Maximum Width Ramp
Question Leetcode 962. Maximum Width Ramp
Given an array A of integers, a ramp is a tuple (i, j) for which i < j and A[i] <= A[j]. The width of such a ramp is j - i.
Find the maximum width of a ramp in A. If one doesn’t exist, return 0.
Note: 2 <= A.length <= 50000 0 <= A[i] <= 50000 Examples: Example 1: Input: [6,0,8,2,1,5] Output: 4 Explanation: The maximum width ramp is achieved at (i, j) = (1, 5): A[1] = 0 and A[5] = 5.
