    for (let i = 0; i < s.length; i++)
    {
        // checking character in string
        if (s.charAt(i) == c)
        res++;
    } 
    return res;
}


    let str= "geeksforgeeks";
    const allCharacters = new Set(str.split(""));
    allCharacters.forEach(character=>{
       console.log(`carater: ${character} ${count(str, character)}`);
    });
