Elements After 5 in Array

Write a C# Sharp program to create an array by taking the elements after element value 5 from a given array of integers.

Sample Solution:

C# Sharp Code:

using System; // Importing the System namespace

namespace exercises // Defining a namespace called 'exercises'
{
    class Program // Defining a class named 'Program'
    {
        static void Main(string[] args) // The entry point of the program
        {               
            // Calling the 'test' method with a given integer array and storing the returned array in 'item'
            int[] item = test(new[] { 1, 2, 3, 5, 7, 9, 11 }); 

            // Outputting the elements of the new array formed after the element '5' if found
            Console.Write("New array: "); 
            foreach (var i in item) // Looping through each element in the 'item' array
            {
                Console.Write(i.ToString() + " "); // Outputting each element followed by a space
            }     
        }               

        // Method to extract elements of an array after the occurrence of the value '5'
        static int[] test(int[] numbers)
        {
            int len = numbers.Length; // Storing the length of the array
            int size = 0; // Variable to store the size of elements after '5'
            int[] post_ele_5; // Array to hold elements after '5'

            int i = len - 1; // Starting from the last index of the array

            // Finding the index of the first occurrence of '5' from the end of the array
            while (i >= 0 && numbers[i] != 5) 
            {
                i--;
            }
            i++; // Incrementing to move to the element after '5'

            size = len - i; // Calculating the number of elements after '5'
            post_ele_5 = new int[size]; // Creating an array with size determined after '5'

            // Storing elements after '5' into the post_ele_5 array
            for (int j = 0; j < size; j++)
            {
                post_ele_5[j] = numbers[i + j];
            }

            return post_ele_5; // Returning the array containing elements after '5'
        }    
    } 
}

Sample Output:

New array: 7 9 11
