The Link -;http://www.codechef.com/viewsolution/6928522 3rd Approach Further optimization, I banged my head a little bit more and got to know about Cartesian Trees from Stanford CS166. I learn that there are only a limited number of block types for RMQ for a size b, there are 4^b ...
or a combination of more than one of these may be needed to arrive at the right solution. However, it should not involve looking into research papers for the problems to be solved. A novice programmer should not be able to solve this, without putting in a lot of effort to learn those ...
In the qualification round of Codechef Snackdown 2017, I was able to solve all the problems and I had a great fun to solve the problem SNAKEEAT. I was so much excited that I had given a post to express my feeling after solving this problem. After that some people asked me on ...
This repository contains the problems I solved on LeetCode, GeeksforGeeks, InterviewBit, Codeforces, CodeChef, CSES, AtCoder, HackerRank, HackerEarth, etc., during my journey to improve my Problem Solving and Coding Ability, aiming to become a Proficient Coder. ...

The solution can easily be framed in a recursive manner - N heads = if 1st flip is a head then N-1 more heads, else N more heads. The probability of 1st head is 1/2. Thus E[N] = (1/2)(E[N-1]+1)+ (1/2)(E[N] + 1) ...
chef, or driving a car. While these get a couple core things right, the rest of the environment; the kitchen, the driver, the chef, is left to interpretation. And the problem isn’t just in metaphors used to teach, but metaphors used in programs themselves. Git commands like “push” ...
You can try Hackerrank or Leetcode website where you can solve problem and you can increase your problem solving ability. If you want to help regarding solution and its explanation you can try this. https://uniquethrowdown.blogspot.com/search/label/HackerRank https://uniquethrowdown.blogspot.co...
A nice tutorial on the algorithm is given on CodeChef blog here. If you read the blog you can see that instead of looking for LCIS in a candidate matrix, we can keep an array that stores the length of LCIS ending at that particular element. Also we keep a lookup previous array that ...
While checking some solutions in python, I noticed that tests of this problem are also very weak, for instance, see this submission: https://www.codechef.com/viewsolution/17348967 . It returned answer is n0 + 1 if n > 40000 and brute-forced otherwise. You can observe that answe...
