Codeforces Edu Round 118 | Good Start but Bad Performance overall | Solving A, B, C

[@PriyanshAgarwal]

Don't mind the background sounds while I am solving problem B please. 😅

[@realnight_bot2536]

U r already master 😊, But just not visible on cf 🙂

[@rithwhickpraharsha6047]

i spent lot of time for like 35 mins in implementing binarysearch for c and solved it

[@taukirahmedkhatri8403]

Solved C in 8 mins then WA on A and B 😂 For me C was easier than max(A, B) even though A and B were straight forward 😂

[@sahilanand30]

Kaise kar lete ho Mera to A hi hua :(

[@taukirahmedkhatri8403]

@@sahilanand30 Just check lectures on Binary Search by ITMO in CodeForces Edu Section. You will never be in a situation where you can't solve Problems on Binary Search (except the problem is extremely hard) 😀

[@parthsaraswat9744]

Did B and C ...TLE and WA on A

[@AbjSir]

max(A,B) lol

[@tushar7305]

I am giving dec long challenge and it is my first contest i have solved first question if it so now should i solve next one question or not?? The problem is that i am unable to solve other question of the contest what should i do???

[@kartiksinghkushwah4991]

I solved 4 for the first time ☺️

[@tushar7305]

How??

[@sayanghosh2883]

I feel Educational contest are little bit tricky than normal Div 2 codeforces round. Is this correct? I want your opinion Priyansh.

[@PriyanshAgarwal]

I am not sure about this. I tend to perform much better in Edu rounds compared to normal rounds. When I was less than 1500 rated, I use to hate Edu rounds honestly.

Observed Lightning of Thor In your eyes while you were solving problem b.

[@shreyanshdokania9008]

I struggled to get even A done for like 1 hr bt solved B in like 10-15 mins after A. I am a beginner , it was my 3rd contest. Is it that bad to be stuck at A for so long?

NO

bro needed some help, I am using an 1440p display for mac m1 and the text look a bit blurry and a bit small, can you tell me which resolution display are you using and if you are using any software to get clear texts?

[@yourbestie4138]

Sir I think u should have move to E after 1 Wa on D ...as E was good graph question ig

[@PriyanshAgarwal]

Totally agree with this. I was just really obsessed with D as it was a DP problem. I almost had it but was struggling to implement it properly.

[@sahilanand30]

I was also thinking about binary search for C

[@tautikagrahari489]

please make your setup for cp for Mac

[@chaitanya812]

Bhaiya you're having which mac and specs (ram)? Also bhaiya is there any laptop in windows compared to mac?

[@AnkitSingh-wq2rk]

depends on task you want to do mac is usually worth if you wanna do ios dev other wise windows lappy with good GPU will do the job most of the times

[@justjie1008]

E was actually easier than D.Just a simple bfs

[@D3vansh]

C nhi hua 😭😭 how can u solve C with binary search

[@vaibhav.polska]

have you tried Standard problems on binary search? Aggressive Cows, Painter's Partition, Book allocation etc. 'C' involved similar concepts.

[@D3vansh]

@@vaibhav.polska thanks for the advice I will do these problems tomorrow 🙏

Minimum Number of Days to Make m Bouquets Find the Smallest Divisor Given a Threshold Divide Chocolate Capacity To Ship Packages In N Days Koko Eating Bananas Minimize Max Distance to Gas Station Split Array Largest Sum Painter's problem Pigs in a barn Page allocation Aggressive Cows Spoj Double Helix SPOJ Here's a mix of leetcode and spoj list for the same. I think these problems are good enough to make you a complete grasp of binary search. All have same concept, with a minor tweak here and there.
