 ## Description
+A **ramp** in an integer array `nums` is a pair `(i, j)` for which `i < j` and `nums[i] <= nums[j]`. The **width** of such a ramp is `j - i`.
+
+Given an integer array `nums`, return the maximum width of a **ramp** in `nums`. If there is no **ramp** in `nums`, return `0`.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
+Input: nums = [6,0,8,2,1,5]
+Output: 4
+Explanation: The maximum width ramp is achieved at (i, j) = (1, 5): nums[1] = 0 and nums[5] = 5.
 ```
