In this case, 6 units of rain water (blue section) are being trapped. Example 1: Input: nums = [1,2,1] Output: [1,2,1,1,2,1] Explanation: The array ans Given n non-negative integers representing an elevation map where the width of each bar is 1, compute how much water it can trap after raining. Help LeetCode design the best way to maximize its total Can you solve this real interview question? Remove K Digits - Given string num representing a non-negative integer num, and an integer k, return the smallest possible integer after removing k digits from num. Example 1: Input: num = "1432219", k = 3 Output: "1219" Explanation: Remove the three digits 4, 3, and 2 to form the new number 1219 which is the smallest. Two strings s and t are isomorphic if the characters in s can be replaced to get t.
