HackSussex runs an annual programming competition where all programmers studying at the University of Sussex compete to answer algorithmic coding puzzles. The first stage is a HackerRank competition where you can flex your knowledge of data structures and algorithms to answer as many questions as you can within a week! The next stage is a 8 player knockout competition where you will go toe to toe with other programmers, which will be streamed online. There is a prize pool involved for the winners of the competition.

@vm221 19 дней назад

Great idea but really needs some work on the execution, for example: -Some of the problems would benefit from a brief code review at the end, rather than cutting straight to the hosts without reflecting at all on the differences in code or approach between the contestants. Even just a 15 second comparative review would be better than cutting to filler talk. -why interview the loser asking them 'if they have anything to say', instead of interviewing the winner about their successful approach? -at the end of the round when it cuts back to the hosts, the competitor info on the screen is obscured Keep it up and looking forward to seeing the next incarnation of the contest.

@@HackSussex Really cool idea, I think it would be a better to put up a veteran knowledgeable coder as the judge, so that they analyse the competitor approach instead of these guys just putting up a voice over of what they are implementing.

I am an Esports fan on most games but this, as a self-taught programmer, I love this more than anything else. Makes my brain analyze more than in games with strategy, but those are still good and fine, they were made for what they are. But this, this is what I want.

Jacopo's solution on R1-G3 is wrong if we take two strings having same alphabets, but different in counts. Eg: s1="aaab", s2="abbb". Here, if we use set to store all alphabets of s1, s2; then we get {a,b}. Difference in positions of characters is two, so Jacopo's solution would return True. But in reality, it's False as s1 has three a's, s2 has three b's. So, we need to take a bit-array or hashmap to store characters and their counts for each string separately, then compare the occurrences for each character.

@jacopocalvi7546 18 дней назад

Damn, you're right. Well spotted!

@meirbek241 17 дней назад

1st condition: return false if strings have not same number of characters 2nd condition: return false if there are more than 1 character mismatch otherwise just return true

@sohantirpude2455 15 дней назад

Yes, you are right. Jacopo's solution is not working on certain cases. But, I think, the approach you mentioned that to store characters and their counts for each string separately, then compare the occurrences for each character, will also fail if s1="abba" and s2="abab". If we match the difference in position of characters then it may work. But in my opinion it's better to create a new string from s2 with swapping and compare with s1.

@user-vs5rh1oz3w 15 дней назад

@@sohantirpude2455i am storing index and since the two strings should have been equal means, the index of alpha should be the same, if it isn't we will swap. in leetcode it's called as buddy strings unordered_mapm; for(int i=0;i

Watching bramble get stun locked on that question was brutal. He managed to cobble together something and was frozen solid for a good 10m. It was interesting to see. The sorting was a trap because if it's a matrix you cannot restructure it. Easiest way to do this generate two sets. One of the original array, the other with the appropriate element in each one. And then check length and voila

33:37 For this question R1-G2 We can first calculate the sum of n numbers using formula and use for loops to check each row is equal to that sum , if it is not equal we can return it on that condition

@alvaroflores4371 23 дня назад

That would expose you to the cases where sum(1 to n) can equal the correct sum, but not contain the required [1 to n]. For example sum of [1,2,3] = 6, but sum of [1,1,4] is also 6. Thus not a valid row.

It's educational and entertaining. please continue on, on your awesome show Only few things I think would improve this, Move that TV behind you guys a little higher so the informations are not blocked by your shoulder. Also when either coder won, run through their code real quick. And lastly maybe position the coders a little better so the introducer is not awkwardly standing and blocking them after introducing them (it's just a tiny change that would improve it in my opinion) Everything else is perfect can't wait for the next videos
