SRM 571 DIV 2, Problem 250

Here a new problem solved by me!

Here the problem statement:

Fox Ciel is playing the popular game ‘Cut the Rope’ on her smartphone. The game has multiple stages, and for each stage the player can gain between 0 and 3 stars, inclusive. You are given a string[] result containing Fox Ciel’s current results: For each stage, result contains an element that specifies Ciel’s result in that stage. More precisely, result[i] will be “—” if she got 0 stars in stage i, “o–” if she got 1 star, “oo-” if she got 2 stars and “ooo” if she managed to get all 3 stars. Return the total number of stars Ciel has at the moment.

Here the constraints:

result will contain between 1 and 50 elements, inclusive.

Each element in result will be one of “—”, “o–”, “oo-”, “ooo”.

Here my approach:

I decided to use two for loops, the first one to read each element, and then another for loop to read each single element inside that, and adding 1 foreach “o” in the loops.

Here my code:

public class FoxAndGame
    {
        public int countStars(string[] result)
        {
            int res = 0;
            for (int i = 0; i < result.Length; i++)
            {
                for (int a = 0; a < result[i].Length; a++)
                {
                    if (result[i][a].ToString() == "o")
                        res++;
                }
            }
            return res;
        }
    }

If you have another approach, please share with me in a comment!

Thank you very much
