Question

I am counting the how many strings are present in the array-

Tags = "the cat the mat the sat";

string[] words = Tags.Split(' ');

int counter = 0;

foreach (string item in words)
{
    if (item != "")
    {
      counter++;

    }
}

However how could I modify my code so that I counted the occurrence of every string.
So for instance –

• “the” = 3
• “cat” = 1
• “mat” = 1
• “sat” = 1

and then store these values some way?

You don’t say what language you use, but what I see it looks like c#. Here is one way to do it.

    Dictionary<string, int> dictionary = new Dictionary<string, int>();
    foreach (string word in words)
    {
        if (dictionary.ContainsKey(word))
        {
            dictionary[word] += 1; 
        }
        else
        {
            dictionary.Add(word,1);
        }
    }
