let arr = []
    for(let i = 1; i <= n; i++){
        if(i%3 != 0 && i%5 != 0){
            arr[i-1] = i.toString()
        }else if(i%5 == 0 && i%3 == 0){
            arr[i-1] = "FizzBuzz"
        }else if(i%3 == 0){
            arr[i-1] = "Fizz"
        }else{
            arr[i-1] = "Buzz"
        }
