#LSPPDay32 Today, I solved the Number of Islands problem using recursive flood fill, sinking connected land cells in all 4 directions to count distinct islands in a 2D grid. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay31 Today, I applied recursion to solve fast exponentiation using divide and conquer to compute power in O(log n) and binary search by recursively halving the search space. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay30 Today, I continued learning recursion in C++ by solving sum of an array and reversing a string, breaking each problem down into smaller subproblems with a clear base case. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay29 Today, I started learning recursion in C++ by implementing two simple problems, fibonacci series and factorial of a number, understanding how a function calls itself with a case to stop. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay28 Today, I built a Trie in C++ from scratch supporting insert, search, prefix matching, autocomplete suggestions, longest common prefix, word frequency tracking and deletion with recursive memory cleanup. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay27 Today, I built a linked list based queue in C++ from scratch with enqueue, dequeue, reverse, min/max traversal and positional insertion all managed manually with raw pointers and a destructor for cleanup. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay26 Today, I simulated a garbage collector in C++ implementing mark and sweep to free unreachable objects, cycle detection using DFS with a visited stack, root tracking, and heap statistics. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay25 Today, I built a custom memory pool in C++ and used it to allocate linked list nodes, implementing merge sort, reverse, sorted insert, middle finder and merge operations all without a single new call per node. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay24 Today, I used C++ triple pointers int*** to build a 2D matrix system from scratch supporting dynamic allocation, transpose, multiplication, flattening, sorting and element search using raw pointer manipulation. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay23 Today, I learned C++ function pointers and dynamic memory allocation, using function arrays for arithmetic operations and managing heap allocated variables, arrays, and matrices with new, delete, and delete[]. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay22 Today, I went deeper into C++ pointers learning double pointers int**, dynamic memory allocation with new and delete[], and passing pointer to pointer to functions to allocate heap arrays. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay21 Today, I started learning C++ pointers. I used & to get a variable's address, * to declare and dereference pointers, modified values by dereferencing, and passed pointers to functions to update variables. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay20 Today, I learned C++ string manipulation by solving the longest palindromic substring problem. I used expand around center with lambdas to check odd and even length cases. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay19 Today, I learned to solve a LeetCode Medium problem, Container With Most Water, using the two pointer technique to shrink the window from both ends while tracking the maximum area formed. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay18 Today, I solved a LeetCode Hard problem, Median of Two Sorted Arrays, using binary search across the smaller array to find the correct partition point in O(log(m+n)) time. Took a while but got there. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay17 Today, I solved 2 LeetCode problems. Valid Parentheses using a stack to match brackets, and Reverse Integer by extracting digits with modulo and checking overflow against INT_MAX. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay16 Today, I solved 2 LeetCode Medium problems which were "Add Two Numbers" after learning linked lists by simulating digitwise addition, and "Valid Anagram" by sorting both strings and comparing them. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay15 Today, I used C++ strings and STL algorithms to perform text analysis which includes converting input to uppercase and lowercase, checking for palindromes, and using a map to count character frequencies. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay14 Today, I used C++ stack to build an expression evaluator, parsing digits and operators, handling precedence with two stacks for numbers and ops, and applying lambdas to compute results in order. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology

#LSPPDay13 Today, I learned C++ priority_queue. I used the default max-heap with push(), top(), and pop(), and created a min-heap using priority_queue<int, vector<int>, greater<int>>. #LearningWithLeapfrog #60DaysOfLearning2026 @lftechnology
