Question

Write a C# program to generate 2 Lists of random 5 elements each containing only binary numbers like 1 or 0 only such that there is only one 1 in the list in any random position and the rest four elements are zeroes. Create another list of 3 elements and such that there are random 1s or 0s. And concatenate these 3 Lists together to produce "one List" named "datablock".

Below is the solution;

using System;
using System.Collections.Generic;
using System.Linq;

namespace ListConcate
{
    class ListConcate
    {
        static void Main(string[] args)
        {
            Random random = new Random(); //create a random object
            List<int> list1 = new List<int>(); //create a list1
            List<int> list2 = new List<int>(); //create a list2

            for(int i=0; i<5; i++) //loop 5 times
            {
                int r = random.Next(0, 2); //genearte random number 0 or 1
                list1.Add(r); //add the random number to list1
            }

            for (int i = 0; i < 3; i++)
            {
                int r = random.Next(0, 2); //genearte random number 0 or 1
                list2.Add(r); //add the random number to list2
            }

            List<int> datablock = list1.Concat(list2).ToList(); //concatinate list1 and list2
            //print datablock
            foreach (var x in datablock)
                Console.WriteLine(x);
            Console.ReadKey();
        }

}

}

sample output:

0
1
1
0
1
1
1
1

Type2 solution:

Below is the solution:

using System;
using System.Collections.Generic;
using System.Linq;

namespace Calculator
{
    class Calculator
    {
        static void Main(string[] args)
        {
            Random random = new Random(); //create a random object
            List<int> list1 = new List<int>(); //create a list1
            List<int> list2 = new List<int>(); //create a list2
            int n = 0;
            bool set1 = true;
            int setNum = 0;
            //do while loop generate the random number 0-1 and only 1 one time
            do
            {
                int r = random.Next(0, 2);
              
                if (set1 == true && r == 1)
                {
                    set1 = false;
                    setNum = 1;
                    list1.Add(r);
                    n++;
                }
                else
                {
                    if (r == 0)
                    {
                        list1.Add(r);
                        n++;
                    }
                }
            } while (n != 5 || setNum != 1); //loop until 1 time 1 and n is 5 times
            Console.Write("\nList1: ");
            foreach (var x in list1)
                Console.Write(x);

            for (int i = 0; i < 3; i++)
            {
                int r = random.Next(0, 2); //genearte random number 0 or 1
                list2.Add(r); //add the random number to list2
            }
            Console.Write("\nList2: ");
            foreach (var x in list2)
                Console.Write(x);

            List<int> datablock = list1.Concat(list2).ToList(); //concatinate list1 and list2
            //print datablock
            Console.Write("\ndatablock: ");
            foreach (var x in datablock)
                Console.Write(x);
            Console.ReadKey();
        }

}

}

sample output:

List1: 00001
List2: 101
datablock: 00001101
