    Hi there team!

    I am trying to find a solution for this with no luck.

    What I am asked to do is to replace every letter from the string "anilina" by it's middle character which is L. So the results gets to be "LLLLLLL", instead of the initial word.

    How can I detect that L in the middle of the string? Thanks!

    Seems like an interview question, but I'll bite. You can just treat the string as an Array of characters. Just get the length, divide it by 2, and that should be the middle character's index.

    String length divided by two

    And should be something near on

    new string . character replace


    But you could for loop that and say if we are not the middle then make me the middle.

    Code (CSharp):
    1.  
    2.         string RESULT = "";
    3.         int I = ANILINA.Length / 2;
    4.         char KEYCHARACTER = ANILINA[I];
    5.         for (int i = 0; i < ANILINA.Length; i++)
    6.         {
    7.             if (ANILINA[i] != KEYCHARACTER && i == I)
    8.             {
    9.                 RESULT += ANILINA[i];
    10.             }
    11.             else
    12.                 RESULT += KEYCHARACTER;
    13.         }
    14.         Debug.Log(RESULT);
    15.
