Code Review Stack Exchange is a question and answer site for peer programmer code reviews. It only takes a minute to sign up. Given an array with n elements, can you sort this array in ascending order using only one of the following operations? The first line contains a single integer, n, which indicates the size of the array. The next line contains integers separated by spaces.

If the array is already sorted, output yes on the first line. You do not need to output anything else. If you can sort this array using one single operation from the two permitted operations then output yes on the first line and then:. Else if it is possible to sort the array by reversing the segment d[l My main question is about reverse iterators. Do you think this affects readability or is the code fine like it is? Any other suggestion? I find the reverse iterators a bit confusing, but I might be a little slow.

That said, I'm probably not the only one, so you wouldn't waste your time looking for a simpler way to express yourself. I'd add that you forgot to handle the case where the input is already sorted, meaning that you could have been overwhelmed yourself.

Problem statement Given an array with n elements, can you sort this array in ascending order using only one of the following operations? Swap two elements. Reverse one sub-segment. Input Format The first line contains a single integer, n, which indicates the size of the array.

If an array can be sorted by either swapping or reversing, stick to the swap-based method. If you cannot sort the array in either of the above ways, output "no" in the first line. Blasco Blasco 5 5 silver badges 16 16 bronze badges.

But converting an iterator to a position is quite easy. I particularly like "Better code" the "no raw loop" section is what you're looking for. I'm really liking it! Sign up or log in Sign up using Google. Sign up using Facebook.

We are going to explain our hackerrank solutions step by step so there will be no problem to understand the code. We will also put comments on every line of code so you can understand the flow of the program. You can practice and submit all HackerRank problems solution in one place.

Find a solution for others domain and Sub-domain. As you already know that this site does not contain only Hacker Rank solution here, you can also find the solution for other programming problems. This helps you to understand the reasoning and actual problem. Here is the list. Here is the list of program challenges that we have to find the answers.

Say "Hello, World! You must check the stringstream hackerrank solution. Strings StringStream Attribute Parser. There are no classes in the C programming language. There is a minor difference in Classes and structure. We are going to cover these solutions in this article. Below is the list of some Standard Template Library programs challenges. Inheritance means inherit An inherited class is called a subclass of its parent class or superclass. So below, we have some Inheritance programs list.

We will take care of it. We have applied to debug of our program, or we can say that we are going to know how to debug our programming code. Now In this section, we are going to solve this and last part as well. So basically, in this section, we have to solve some competitive Hackerrank programming challenges. You can find a more competitive question in this section that is recently asked. Recently oz has found a magical string consisting of the single-digit "1".

Write a function which takes an array and emits the majority element if it existsotherwise prints none. Finally, we are now, in the end, I just want to conclude some important message for you. In the last section, maybe you will find some other programming competitive website Hacker Earth solutions, so please ignore that.

My simple solution of the order log nit passed all test cases. My logic was that there was a pattern between the actual time and the time displayed on the stop watch. Am I missing something here? Many of the solutions here seem to take complex approaches. You have to search for the cycle your given time is in.

First cycle has 3 "slots", second has 6 and so on. No loops. Only few math ops. To make it might be not soooo easy, but trying to explain it even more. Hope this helps figuring out to finish. This is Geometric progression of Power of Two, i. Logarithm is required to find N-th term or the nearest term of Geometric progression. See another example. I knew I was overcomplicating things. You did in 5 lines what took me about Very elegant.

It passes all the test cases and for each iteration, n is cut down in half. Hence a log complexity. It did take me a second try since initially, I did a serial subtraction of t, but that was orders slower and forced me to think about the number pattern. Your solution is good, works in many languages, but int Java 7 it times out for some test cases, so in that language a faster solution is needed. Seems to me that the timeout period may have been too short because your solution is O log n.

Someone's hint about inadvertently using an integer in the main loop turned out to work for me too against the time-out. Anyway, by the time I noticed that I had a working code for performing binary search for exponents rather than looping up. Overkill for sure, but a fun exercise all in all. Genius level intellect! Coming to a conclusion to there is a pattern is fine. But to execute it with such ease, nice. Had the same solution but in C. For some reason I still get runtime errors.

Switched to Python using my same solution and it passed just fine. Use long long int to store values of integers related to t if you are going through the above code logic. This is actually a math problem. So, the problem is O 1. It took me a lot of time to figure out how to calculate the first value of the colum.

It is really O 1 - just take one log2 and few other simple math operations. Loop is really needn't at all.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
