Episode 25 - Desert Wind

One of the viewers, Mikhail Goncharov, has happily contributed time links to an old episode of algorithms live. You can see the links in the description of the knapsack episode. It is now way easier to navigate the episode to find a useful subtopic being discussed. This expanded description also gives a nice outline so you get an overview of an old episode. Thank you so much! If anyone else would like to contribute similar time links, just send me an overview of the episode in this form (either PM through Codeforces or YouTube):

00:00 Introduction
03:23 Technique 1
5:31 Problem Name
13:21 Technique 2
14:30 Coding

I really appreciate this type of contribution. If you can contribute to even one episode, please do!

In this week's episode, I will be discussing an old problem that I find interesting, Desert Wind. You can the problem statement here:

The episode should be a bit shorter than usual but I hope you will all still enjoy it. I should be done right before the start of this week's Codeforces Educational Round.

See you live! (time, stream)

     Contact Dr. Odunga at odungaspelltemple@gmail.com OR Whats App/CALL +2348167159012

    I got my ex husband back to me and also got fertile and gave birth to twin girls after 12 years of marriage.
    When I came online last year, I saw a testimony about Doctor ODUNGA and how he has been helping people with marriage issues and I decided to contact him. We spoke on email at odungaspelltemple@gmail.com and later he gave me his WhatsApp number which is +2348167159012. He assured me he would help me get my ex husband back after 3 years of no contact. Doctor Odunga is the best spell caster I must say. My husband called me after 24 hours of contact. The third day, I received natural herbs for fertility and after using it, I became fertile and conceived. I and my husband reconnected, had sex and I was pregnant. Presently I am happy to say I am the mother of twin girls and this is ALL THANKS TO DOCTOR ODUNGA. I came online to say this If you need help, I believe you are saved with this man.

    Am so happy to testify about a great spell caster that helped me when all hope was lost for me to unite with my ex-girlfriend that I love so much. I had a girlfriend that love me so much but something terrible happen to our relationship one afternoon when her friend that was always trying to get to me was trying to force me to make love to her just because she was been jealous of her friend that i was dating and on the scene my girlfriend just walk in and she thought we had something special doing together, i tried to explain things to her that her friend always do this whenever she is not with me and i always refuse her but i never told her because i did not want the both of them to be enemies to each other but she never believed me. She broke up with me and I tried times without numbers to make her believe me but she never believed me until one day i heard about the DR.

  9. I really want to thank Dr Emu for saving my marriage. My wife really treated me badly and left home for almost 3 month this got me sick and confused. Then I told my friend about how my wife has changed towards me. Then she told me to contact Dr Emu that he will help me bring back my wife and change her back to a good woman. I never believed in all this but I gave it a try. Dr Emu casted a spell of return of love on her, and my wife came back home for forgiveness and today we are happy again. If you are going through any relationship stress or you want back your Ex or Divorce husband you can contact his whatsapp +2347012841542 or email emutemple@gmail.com website: Https://emutemple.wordpress.com/

  11. I am here to enlighten everyone about the good works of Dr Ilekhojie. Me and my ex wife have been having issues for the best part of 2 years now and we have tried all counseling and talking with our parents but nothing was working. We fight over everything and separation was imminent until I saw a review of Dr Ilekhojie. I contacted him and informed him of my condition. He promised to perform a reconciliation ritual which will ensure that the connection between me and my wife is restored. It has been a week now since I have sort his help and things are starting to get better between me and my wife. We have started living in the same bedroom again and we have both informed our lawyers to put the divorce plans on hold. I am so happy now that I can be able to enjoy my wife again. Reach out to Dr Ilekhojie if you have problems in your marriage. Email: gethelp05@gmail.com or WhatsApp/Telegram/Viber +2348147400259
