This is also a popular LeetCode coding problem, which I haven't tried to submit my solution, you can and if you need more coding problems, particularly based upon bit manipulation then LeetCode has some good ones. If you need some resources to level up your essential skills, the following...
The main goal of using DSA is to solve problems effectively and efficiently. How do you assess if your program is efficient? This is where complexities come in, and there are two types:Time Complexity: It measures the time needed to execute the code. Space Complexity: It indicates the ...
In short, mostly you only need to use codeforces (no matter what contest you're training for), find a rating range where you can solve around ~30-40% of the time on your own, and just grind down the problem set tab in reverse order of id (the default sorting). Also take part in...
This course will teach you 15 essential coding patterns like sliding window, merge interval, fast and slow pointers, etc which can be used to solve 100+ Leetcode problems. Knowing these patterns and how to apply them will certainly boost your chances in real coding interviews. ...
When you learn dynamic programming in the early stage, you can try to solve it with memoization first. Then transform it into dynamic programming, so that you will feel it when you practice it a few times. After that, you can practice scrolling the array. This technique is very useful and...
So even if you are unable to solve problems, just keep at it. Learn from the solutions of other people, and visualize different methods to solve a single problem. Step 4: Decide the Career Path While you’re trying to understand how to become a Python developer, you must keep in mind...
This leetcode's problem is a favorite question of coding interviews. The data structure we are going to work with is Singly LinkedList. It's super fun. Note: We are not going to use the inbuilt LinkedList class of C# because that is a doubly linked list....
But you can find the questions of the challenge with Google. Some people already uploaded what they did. Find the questions and try to solve them on your own, and compare your solution with others. This is like an awesome private teacher who guides you on what to do. ...
Learning software programming can be rewarding, yes. But it can be fun, too, with activities that go beyond simply reading instructional materials and writing lines of code. With coding games and educational apps, you can learn new concepts, solve coding challenges, and practice what you've lea...
