C# Sharp Exercises: Number of times a substring appeared in a string

C# Sharp String: Exercise-63 with Solution

Write a C# Sharp program that takes a string that is a repetition of a substring. Count the number of times the substring appeared.

Sample Data:
("aaaaaa") -> 6
("abababab") -> 4
("abcdabcdabcd") -> 3

Sample Solution-1:

C# Sharp Code:

using System;
using System.Linq;
namespace exercises
{
    class Program
    {
        static void Main(string[] args)
        {
            string text = "aaaaaa";
            Console.WriteLine("Original strings: " +text);
            Console.WriteLine("Number of times a substring appeared in the said string: " + test(text));
            text = "abababab";
            Console.WriteLine("Original strings: " + text);
            Console.WriteLine("Number of times a substring appeared in the said string: " + test(text));
            text = "abcdabcdabcd";
            Console.WriteLine("Original strings: " + text);
            Console.WriteLine("Number of times a substring appeared in the said string: " + test(text));
        }
        public static int test(string text)
        {
            return text.Split(text[0]).Count() - 1;
        }
    }
} 

Sample Output:

Original strings: aaaaaa
Number of times a substring appeared in the said string: 6
Original strings: abababab
Number of times a substring appeared in the said string: 4
Original strings: abcdabcdabcd
Number of times a substring appeared in the said string: 3

Sample Solution-2:

C# Sharp Code:

using System;
using System.Linq;

namespace exercises
{
    class Program
    {
        static void Main(string[] args)
        {
            string text = "aaaaaa";
            Console.WriteLine("Original strings: " +text);
            Console.WriteLine("Number of times a substring appeared in the said string: " + test(text));
            text = "abababab";
            Console.WriteLine("Original strings: " + text);
            Console.WriteLine("Number of times a substring appeared in the said string: " + test(text));
            text = "abcdabcdabcd";
            Console.WriteLine("Original strings: " + text);
            Console.WriteLine("Number of times a substring appeared in the said string: " + test(text));
        }
        public static int test(string text)
        {
            int ctr = text.IndexOf(text[0], 1);
            return ctr < 0 ? 1 : text.Length / ctr;
        }
    }
}

Sample Output:

Original strings: aaaaaa
Number of times a substring appeared in the said string: 6
Original strings: abababab
Number of times a substring appeared in the said string: 4
Original strings: abcdabcdabcd
Number of times a substring appeared in the said string: 3
