I have discussed the priority queue and implementations of queue, vector. Now, we are gonna discuss about min heap, also known as a priority queue. So, what’s this data structure? It has 4 main methods: size() - returns the number of the elements front() - return the current minimum element pop() - deletes the current minimum element push(element) - insert new element to the heap How do we implement this?...
We discussed queue implementation in here and about vector here. Like a queue we will now discuss vector implementation in this post. A vector is a simple data structures similar to an array, but its size is dynamic. The main feature is that we can access any element in vector in O(1) time. Vector has three main methods size() - returns the number of elements. push(element) - inserts a new element at the back of the vector....
We talked about queue in this post. Now, I’m gonna explain how to implement this data structure. What we need is a basic understanding of pointer and memory. Queue has 4 main methods size() - returns the number of the elements top() - returns the first element of the queue pop() - deletes the first element push(element) - insert new element back of the queue How hard can it be?...
How to learn programming? In my experience, I have familiarized myself with the basics of programming and understand the fundamental concepts, then I start solve competitive programming problems. To begin with, it’s recommended to focus on learning the fundamentals of C and C++ programming languages, as they provide a solid foundation. As I mentioned earlier, problem-solving skills are paramount. Platforms like Hackerrank, Codeforces, and Codechef are excellent resources to enhance your problem-solving abilities....
