Day 10 of logic building and cpp basics revision.....☠️💻 Step 1: int arr[] = {5, 10, 15}; Array elements: arr[0] = 5 arr[1] = 10 arr[2] = 15 _____________________________________________________ Step 2: int *p = arr; Pointer p stores the address of arr[0]. So initially: p → 5 _____________________________________________________ Step 3: *++p Operator precedence matters here. ++p Pre-increment moves the pointer FIRST. So p now points to arr[1]. Now: p → 10 _____________________________________________________ Step 4: *p Dereference the new pointer location. Value at arr[1] is 10. Final Output: 10 _____________________________________________________ #cplusplus #programming #learntocode #logicBuilding #logicTesting

Day 8 of Cpp basics revision...... ☠️ Explanation Step 1: There are two overloaded functions: fun(int) fun(double) ---------------------------------------------------- Step 2: In main(), we call: fun(5.0f); ---------------------------------------------------- The literal 5.0f is of type float. ---------------------------------------------------- Step 3: Now the compiler looks for the best match. Available options: float → int (standard conversion) float → double (standard conversion) ----------------------------------------------------- Step 4: Between these two, conversion from float → double is a promotion (preserves precision). float → int would lose the decimal part, so it is a worse match. ---------------------------------------------------- Step 5: Because float → double is a better conversion than float → int, the compiler selects: fun(double) ---------------------------------------------------- Step 6: Therefore, the output is: Double ---------------------------------------------------- #coding #cplusplus #logicBuilding #programming #softwaredeveloper

✅ Correct Answer: A) 10 Step 1: int x = 10; A variable x is created inside main() and initialized with value 10. Step 2: change(x); The function is called and x is passed as an argument. Step 3: void change(int x) The parameter x receives a COPY of the original variable. This is called Pass by Value. Step 4 (Inside function): x = 20; Only the copied variable is changed. The original x inside main() remains unchanged. Step 5: cout << x; We print the original variable from main(). Since it was never modified, it still holds 10. Final Output: 10 Key Concept: Pass by Value does NOT modify the original variable. If it were written as: void change(int &x) Then the output would be 20 (Pass by Reference). #cpp #cplusplus #programming #logicBuilding #softwareengineer

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. If this clarified the logic, stop reading and impl
