Leetcode: Maximum Width Ramp

Maximum Width Ramp



Similar Problems:


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.

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.

Example 2:

Input: [9,8,1,0,1,9,4,0,4,1]
Output: 7
Explanation: 
The maximum width ramp is achieved at (i, j) = (2, 9): A[2] = 1 and A[9] = 1.

Note:

  1. 2 <= A.length <= 50000
  2. 0 <= A[i] <= 50000
