Checker result: "13 7 19 11 11 8 12 6 9 7 14 12 10 8 10 11 13 9 9"

My result : "13 7 19 11 11 8 12 6 9 7 14 12 10 8 10 11 13 9 9"

My code: using System;

public class Program { public static void Main() {
int length = Convert.ToInt32(Console.ReadLine()); string[] t = new string[length]; for(int i = 0; i<length;i++){ string line = Console.ReadLine(); t[i] = line; } int[] f = new int[t.Length];

    for (int i = 0; i<t.Length;i++){
        f[i] = 0;
        foreach(char c in t[i]){
            if(c == 'a'||c == 'e'||c == 'i'||c == 'o'||c == 'u'){
               f[i]++;
            }
        }
    }
      for(int i = 0; i<t.Length;i++){
        Console.WriteLine(f[i]+" ");
    }

}

}

Yeah that really bamboozled me
