Leetcode permutation in string . . . #dsa #leetcode #lc438 #slidingwindow #hashmaps 🔍 Permutation in String — Pattern & Code Explanation 🚀 Problem Overview Given two strings s1 and s2, return true if s2 contains any permutation of s1. In simple terms: check if any substring of s2 is an anagram of s1. --- 🧠 Pattern Used: Sliding Window + Frequency Map 💡 Core Idea We compare character frequencies instead of generating permutations. Steps: 1. Count character frequencies of s1. 2. Use a fixed-size sliding window over s2 with the same length as s1. 3. Update window counts as it moves. 4. If window frequency matches s1 frequency at any point, a permutation exists. --- ⏱ Complexity Time: O(n) where n is length of s2 Space: O(1) because only lowercase letters are stored Efficient and scalable. --- 🧩 Code Explanation Step 1: Count characters in s1 s1count stores frequency of each character in s1. Step 2: Sliding window over s2 window stores frequency of current window characters. Step 3: Expand window Each new character in s2 is added to the window count. Step 4: Maintain window size Once window size exceeds length of s1: • Remove leftmost character • Decrease its count • Delete if count becomes zero This keeps the window size fixed. Step 5: Compare maps If window equals s1count, we found a permutation. --- 🧠 Mental Model Instead of checking all permutations, ask: Does any window in s2 have the exact same character counts as s1? --- 🎯 Example s1 = "ab" s2 = "eidbaooo" Window movement: ei → no id → no db → no ba → match found → return true --- ⚠️ Common Mistakes Using sorting for each window causes slowdown Not removing zero-count characters breaks comparison Letting window grow beyond s1 length ruins logic --- 🔥 Why This Approach is Superior Brute force permutations are factorial time and impractical. Sliding window with frequency maps gives linear time. --- 🏁 Final Thoughts This pattern is critical for: • Anagram detection • Substring search problems • Pattern matching in strings • Efficient window-based algorithms Master this or struggle with string problems in interviews.

✅ Solved LeetCode Problem 696 – Count Binary Substrings Today I solved LeetCode 696, a great problem focused on string manipulation and pattern recognition. The task is to count the number of non-empty substrings that have equal numbers of consecutive 0’s and 1’s, and all the 0’s and 1’s in those substrings are grouped consecutively. 🔹 This problem helps improve understanding of: String traversal techniques Counting consecutive characters Optimizing from brute-force to efficient linear solution (O(n)) 💡 The key idea is to track consecutive groups of 0’s and 1’s and count valid pairs based on the minimum of adjacent group lengths. Another step forward in mastering Data Structures & Algorithms 🚀 Consistency is the key! #leetcode #dsa #softwareengineer #programmer #java
