Leetcode Two Pointers. Can you solve this real interview question? Interleaving String - G

Can you solve this real interview question? Interleaving String - Given strings s1, s2, and s3, find whether s3 is formed by an interleaving of s1 and s2. An interleaving of two strings s and t is a configuration where s and t are divided into n and m substrings respectively, such that: * s = s1 + s2 + + sn * t = t1 + t2 + + tm * |n - m| <= 1 * The interleaving is s1 + t1 + s2 + t2 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.

Example 1: Input: height = [0,1,0,2,1,0,1,3,2,1,2,1] Output: 6 Explanation: The above elevation map (black section) is represented by array [0,1,0,2,1,0,1,3,2,1,2,1]. Example 1: Input: nums = [1,2,1] Output: [1,2,1,1,2,1] Explanation: The array ans Can you solve this real interview question? 3Sum - Given an integer array nums, return all the triplets [nums[i], nums[j], nums[k]] such that i != j, i != k, and j 1.
