LeetCode Daily – Day 36: Trapping Rain Water (Part 2) In Part 1, we saw what the question is saying and also understood when water gets trapped and the formula behind it: 👉 water[i] = min(leftMax, rightMax) - height[i] Now let’s actually solve it using two approaches 👇 ✅ Approach 1: Brute Force For every index i, we check: 🔹 leftMax: Maximum height from 0 to i 🔹 rightMax: Maximum height from i to n-1 Then apply: water[i] = min(leftMax, rightMax) - height[i] Time Complexity: O(n²) – Because for each index, we run two loops to find leftMax and rightMax. ✅ Approach 2: Using Prefix Arrays (Optimized to O(n)) To avoid recalculating leftMax and rightMax every time, we precompute them using two arrays: 1️⃣ leftMax[]: We fill this from left to right, storing the tallest bar seen so far. 2️⃣ rightMax[]: We fill this from right to left, storing the tallest bar seen from the right. Now we calculate trapped water at each index using: 👉 min(leftMax[i], rightMax[i]) - height[i] 🔁 Do this for all indices and add it up to get the total trapped water. Time Complexity is O(n). This is way better than brute-force but here we are using extra space. In Part 3, we’ll go even deeper and solve this with the Two Pointer approach, no extra space needed.

LeetCode Daily - Day 36 : Trapping Rain Water (Part 1) We are given an array that represents the height of bars. Our task is to calculate how much water can be trapped between these bars after it rains. But before solving this question, we need to know when does water actually get trapped? Let’s break it down. Water can only get trapped if a shorter bar is surrounded by taller bars on both sides. And to calculate the water trapped at each index, we need to know two things: 👉 The tallest bar to the left of that index, call it leftMax 👉 The tallest bar to the right of that index, call it rightMax Once we know both, the formula is simple: water[i] = min(leftMax, rightMax) - height[i] Let’s say: leftMax = 4, rightMax = 6, and height[i] = 2 Then water trapped at index i will be: min(4, 6) - 2 = 2 units Pretty intuitive, right? But here’s the catch… How do we efficiently find leftMax and rightMax for every index? In the next part, we’ll explore two powerful approaches: ✅ One brute-force way (just to understand the logic clearly) ✅ And one optimized using prefix arrays So make sure to save this post, and stay tuned for Part 2 where we dive into code and logic. #dsa #java #leetcode #datastructure #javaprogramming #logicbuilding #codingwithyash #algorithms #leetcodesolution #interviewprep

🌟 Day 16: Daily LeetCode Challenge 📚 Today's Problem: Koko Eating Bananas Today was all about finding the right balance with Koko's banana eating speed. The goal: determine the minimum speed at which Koko can eat all the banana piles within a given number of hours. 🔑 Key Points: 1. Utilized a binary search approach to minimize Koko's eating speed. 2. Calculated the total hours needed for each possible speed and compared it with the given limit. 3. Focused on finding the lowest speed that still allows Koko to finish in time. #KokoEatingBananas #LeetCode #Python #softwareengineer #programming #coding #developer #tech #problemSolving #dailyprogress #code #selftaught #pythoncoding #binarysearch #optimization
