Assalomu aleykum!
Mening ismim Hojimurod.
Ayni damda men IT sohasida Java va .NET backend dasturchi sifatida o'z faoliyatimni olib boryapman.
Va Albatta shu sohaga oid ma'lumotlari yetkazama!
Agar ma'lumotlarim isga Manfaatli bo'lsa hursandman😊😊😊

Do'stlar biz albatta algoritmik masalalarsiz Dasturlashni tasavvur eta olmaymiz.
Unda "ODOP"(One Day One Problem) Challangeda qatnashamiz degan umidda har kuni Leetcodedan bitta masalani tanlab olamiz!

Unda boshladik!
Sana: 03.08.2024
Mavzu: Array
Masala:
https://leetcode.com/problems/two-sum/description/

Assalomu aleykum!
Bugungi Leetcode kunlik masalasi: https://leetcode.com/problems/minimum-time-difference/?envType=daily-question&envId=2024-09-16
Va men uni yechgan holda birinchi olovchamni qo'lga kiritdim.

Solution On C# :

public class Solution {
    public int FindMinDifference(IList<string> timePoints) {
        int[] c = new int[timePoints.Count];
        int k = 0;
        foreach(var time in timePoints){
            string[] a = time.Split(':');
            int b = Int32.Parse(a[0]) * 60 + Int32.Parse(a[1]);
            c[k] = b;
            k++;
        }

        Array.Sort(c);
        int min = Int32.MaxValue;

        for(int i = 0;i < c.Length- 1;i++)
        {
            for(int j = i + 1;j < c.Length;j++){
                int min1 = Math.Abs(c[i] - c[j]);
                int min2 = c[i] + 1440 - c[j];
            
                if(min > min1){
                    min = min1;
                }

                if(min > min2){
                    min = min2;
                }
            }
        }

        return min;
    }
}

Assalomu aleykum!
Bugungi Kunlik masala Easy darajada ekan.
Bizi ham o'ylashdimi deymana😄😄😄
https://leetcode.com/problems/uncommon-words-from-two-sentences/description/?envType=daily-question&envId=2024-09-17

Hamma narsa ham biz o'ylaganchalik oson emas ekan. Oddiy darajadagi bir misolni ishlaguncha qanchalar bo'shliqlarim ko'p ekanligini anglab yetyapman.
Bizda esa aslo taslim bo'lish yo'q va Ikkinchi Leetcode coinga ham ega bo'ldik😊

public class Solution {
    public string[] UncommonFromSentences(string s1, string s2) {
        string s = s1 + " " + s2;

        string[] a = s.Split(' ');

        string z = String.Empty;
        

        for(int i = 0;i < a.Length;i++)
        {
            bool k = false;
            for(int j = 0;j < a.Length;j++)
            {
                if(i != j && a[i].Equals(a[j]))
                {
                    k = true;
                    break;
                }
            }
            if(!k){
                z += " " + a[i].ToString();
            }
        }

        string[] str;

        if(string.IsNullOrWhiteSpace(z.Trim()))
        {
            str = new string[0];
        }else
        {
            str = z.Trim().Split(" ");
        }
        return str;
    }
}

HashMap haqida maqola yozdim

Uning ortidagi nazariya va zamonaviy dasturlash tillaridagi implementatsiyalari haqida batafsil o’qishingiz mumkin.

Link: https://asadullo.com/blog/hashing/

@solvemproblr

Asadullo aka tomonidan yozilgan bu maqolani o'qib chiqdim.

It is Perfect!

Bir marotaba o'qiysiz va HashMap ning yaratilish tarixi va uni qurishdagi asosiy g'oyalarni va o'zi HashMap qanday muammolrga yechim bo'la olishini tushunib olasiz.
Faqat HashMap Funksiyalarini o'rganib uni o'zingiz yoqtirgan dasturlash tilida implment qilish qoladi xolos!

Do'stlar bugun bir Companiyaning Algoritmik interview siga qatnashdim.
2 soat vaqt va 4 ta masala.
Qariyb 2 tasini ishlay oldim.

Bu masalalar haqida albatta post qilaman. Inn Shaa Allah.

Tushunib yetyapmanki IT olami juda keng. Bir tomonda Project qilayotgan bo'lsang bir , tomonda Algoritmik masala ishlashing kerak. Va ularning bari senga zavq bag'ishlaydi.

Alloh ilmimizni ziyoda qilsin. Amiiyn.

Assalomu aleykum Hammaga xarli tong.
Demak kunimizni Leetcode Day problem bilan boshlaymiz. Qiyinchilik darajasi middle ekan bugun:
https://leetcode.com/problems/largest-number/description/?envType=daily-question&envId=2024-09-18

middle darajadagi misolni yechish oson emas ekan do'stlar fikrlaringizni kutib qolaman qariyb 1 soatdan beri shu masala bilan bandman.

Finallay I get three's coins in Leetcode!

Bugungi kunlik masalani ham yechdik. Qariyb ikki soatlik urinish samarasiz ketmadi.
Bu jarayonda Convert functionlar bilan ko'p ishladim.

BUgungi masalaning yechimini sizlar bilan ulashmoqchiman.

Do'stlar men ikki soat davomida 85 qator code yozib ishlagan masalamni bitta Professional bro Lambda Expression bilan roppa - rosa 5 barobar kam yani 17 qator bilan ishlab qo'yibdilar😱.
Yomon alam qiladi-a!
Lekin bu usulni ham o'rganib oldim juda zo'r usul ekan bitta logika va hammasi tamom.
