C# Sharp Basic Algorithm Exercises: Create a new array of integers and length 1 or more

C# Sharp Basic Algorithm: Exercise-99 with Solution

Write a C# Sharp program to create a new array of integers and length 1 or more. The length of the new array will be double length of an given array and all the elements are 0 except the first  element which is equal to first elements of the given array.

Sample Solution:-

C# Sharp Code:

using System;
namespace exercises
{
   class Program
    {       
        static void Main(string[] args)
        {
          int[] item = test(new[] { 10, 20, -30, -40, 30 });            
           Console.Write("New array: ");         
           foreach(var i in item)
            {
               Console.Write(i.ToString()+" ");
            }          
        }        
       public static int[] test(int[] nums)
          {
            int elements = nums.Length * 2;
            int[] doubleNums = new int[elements];

            doubleNums[0] = nums[0];
            return doubleNums;
          } 
   }
} 

Sample Output:

New array: 10 0 0 0 0 0 0 0 0 0

Previous: Write a C# Sharp program to check if a given array of integers and length 2, does not contain 15 or 20
Next: Write a C# Sharp program to check a given array of integers and return true if the array contains 10 or 20 twice. The length of the array will be 0, 1, or 2.s
