C++ Day 39

  C++ Day 39 STL Containers (Deep Understanding & Real Usage) Till now, you already know arrays, vectors, loops, and STL algorithms. Today, we go one step deeper and understand STL containers , which are the backbone of modern C++ programming. In real projects and competitive coding, choice of container matters a lot. 1. What are STL Containers? STL containers are data structures provided by C++ to store data efficiently. They handle: memory management resizing element access performance optimization You focus on logic , not memory handling. 2. Categories of STL Containers STL containers are mainly divided into: Sequence Containers Associative Containers Unordered Containers Container Adapters 3. Sequence Containers These store data in sequence . 3.1 Vector Most used container in C++. vector< int > v; Key Features: Dynamic size Contiguous memory Fast random access Slower insertion in middle Example: v. push_...

Hope

Title: The Hope's Power
One of the most potent and crucial forces in the human experience is hope. It is the light that steers people out of gloomy times, the inner power that urges them to keep going even if everything looks lost. Unlike momentary feelings, hope is everlasting; it dwells in the heart and mind, so influencing our perspective and driving our need for a better tomorrow.

Hope inspires individuals to confront challenges. Hope lets us have faith in recovery, in healing, or in new beginnings when we are sick, grieving, or fighting. It gives a cause to keep on despite reality rather than rejecting it. Driven by the conviction that a better future is feasible, history offers examples of people and societies that have endured unfathomable suffering—wars, disasters, persecution.

Furthermore motivating is hope. It fosters ideas, drives development, and promotes creativity. While activists want for justice and change, students hope for achievement in their academics and scientists want to find cures for ailments. There would be no cause to improve or aspire without hope. It is the groundwork on which visions are developed and activities are undertaken.

Resilience is also promoted by hope. People who remain hopeful are more likely to recover from setbacks and keep forward. It helps people to deal with life's unknowns by serving as a shield against sadness and depression. In this sense, hope increases not only emotional well-being but also individual and group strength.

Hope, nevertheless, must be accompanied by action. Hope alone cannot transform the earth, but it can spark the efforts that do. Extraordinary possibilities become available when individuals combine hope with bravery, labor, and resolve.

Finally, hope is a force that shapes both our lives and our planet, not only a feeling. It connects us to the belief that the future holds promise, inspires us to act, and helps us to resist. Hope is not naïve; it is vital in a world of difficulties. Change, healing, and development are all possible as long as hope is present.

C++ Day 33

  C++ Day 33: Smart Pointers & Memory Management 🔹 1. wherefore forward pointers in c++ hand-operated green / cancel is error-prone: memory leaks 🧠 double deletes ❌ dangling pointers 💥 smart pointers care store mechanically exploitation raii (Supply skill is initialization) 🔹 ii. Types of Smart Pointers in C++ ✅ std::unique_ptr Sole ownership of a Supply. Cannot be copied. Automatically deletes the Supply when it goes out of scope. cpp Copy Edit #include  unique_ptr ptr1 = make_unique(10); cout << *ptr1 << endl; // 10 You can transfer ownership: cpp Copy Edit unique_ptr ptr2 = move(ptr1); ✅ std::shared_ptr Shared ownership multiple shared_ptrs can point to the same object. Uses reference counting to track how many owners. cpp Copy Edit shared_ptr p1 = make_shared(100); shared_ptr p2 = p1;  // Reference count = 2 When count goes to 0 memory is released. ✅ std::weak_ptr Non-owning reference to a shared_ptr-managed object. Used to break cyclic references ...

CSES Increasing Subsequence solution

 You are given an array containing  n n n integers. Your task is to determine the longest increasing subsequence in the array, i.e., the longest subsequence where every element is larger than the previous one. A subsequence is a sequence that can be derived from the array by deleting some elements without changing the order of the remaining elements. Input The first line contains an integer n n n : the size of the array. After this there are n n n integers x 1 , x 2 , … , x n x_1,x_2,\ldots,x_n x 1 ​ , x 2 ​ , … , x n ​ : the contents of the array. Output Print the length of the longest increasing subsequence. Constraints 1 ≤ n ≤ 2 ⋅ 1 0 5 1 \le n \le 2 \cdot 10^5 1 ≤ n ≤ 2 ⋅ 1 0 5 1 ≤ x i ≤ 1 0 9 1 \le x_i \le 10^9 1 ≤ x i ​ ≤ 1 0 9 Example Input: 8 7 3 5 3 6 2 9 8 Output: 4 #include < bits / stdc ++. h > using namespace std ; void solve (){ int n ; cin >> n ; vector <int> arr ( n ); for ( int i = 0 ; i < n ; i ++)...
