Problem Statement

You start with the number 0 and you want to reach the number N.

You can change the number, paying a certain amount of coins, with the following operations:

Multiply the number by 2, paying A coins.

Multiply the number by 3, paying B coins.

Multiply the number by 5, paying C coins.

Increase or decrease the number by 1, paying D coins.

You can perform these operations in arbitrary order and an arbitrary number of times.

What is the minimum number of coins you need to reach N?

You have to solve T testcases.

Constraints

1 \le T \le 10

1 \le N \le 10^{18}

1 \le A, B, C, D \le 10^9

All numbers N, A, B, C, D are integers.

Input

The input is given from Standard Input. The first line of the input is

T

Then, T lines follow describing the T testcases.
Each of the T lines has the format

N A B C D

Output

For each testcase, print the answer on Standard Output followed by a newline.

23441258666

For the first testcase, a sequence of moves that achieves the minimum cost of 20 is:

Initially x = 0.

Pay 8 to increase by 1 (x = 1).

Pay 1 to multiply by 2 (x = 2).

Pay 1 to multiply by 2 (x = 4).

Pay 2 to multiply by 3 (x = 12).

Pay 8 to decrease by 1 (x = 11).

For the second testcase, a sequence of moves that achieves the minimum cost of 19 is:

Initially x = 0.

Pay 8 to increase by 1 (x = 1).

Pay 1 to multiply by 2 (x = 2).

Pay 2 to multiply by 5 (x = 10).

Pay 8 to increase by 1 (x = 11).

;;
;; Basic usage:
;;
;; (with-cache (:hash-table :test #'equal :key #'cons)
;;   (defun add (a b)
;;     (+ a b)))
;; This function caches the returned values for already passed combinations of
;; arguments. In this case ADD stores the key (CONS A B) and the returned value
;; to a hash-table when (ADD A B) is evaluated for the first time. ADD returns
;; the stored value when it is called with the same arguments (w.r.t. EQUAL)
;; again.
;;
;; The storage for cache can be hash-table or array. Let's see an example for
;; array:
;; (with-cache (:array (10 20 30) :initial-element -1 :element-type 'fixnum)
;;   (defun foo (a b c) ... ))
;; This form stores the value of FOO in an array created by (make-array (list 10
;; 20 30) :initial-element -1 :element-type 'fixnum). Note that INITIAL-ELEMENT
;; must always be given here as it is used as the flag expressing `not yet
;; stored'. (Therefore INITIAL-ELEMENT should be a value FOO never takes.)
;;
;; If you want to ignore some arguments, you can put `*' in dimensions:
;; (with-cache (:array (10 10 * 10) :initial-element -1)
;;   (defun foo (a b c d) ...)) ; then C is ignored when querying or storing cache
;;
;; Available definition forms in WITH-CACHE are DEFUN, LABELS, FLET, and
;; SB-INT:NAMED-LET.
;;
;; You can trace the memoized function by :TRACE option:
;; (with-cache (:array (10 10) :initial-element -1 :trace t)
;;   (defun foo (x y) ...))
;; Then FOO is traced as with CL:TRACE.
;;

;; TODO & NOTE: Currently a memoized function is not enclosed with a block of
;; the function name.

;; FIXME: *RECURSION-DEPTH* should be included within the macro.
