//    return "A"
//     }else{
//         return "no"

    // }
let firstChar = s[0]

    switch (true) { case a.find(item => item === firstChar) !== undefined: letter = "A"; break; case b.includes(firstChar): letter = "B"; break; case c.includes(firstChar): letter = "C"; break; default: letter = "D"; }

    return letter;

    }

    commented code is for understanding
