Question

You're given an array arr. Apply the following algorithm to it:

 

find intervals of consecutive prime numbers and consecutive non-prime numbers;

replace each such interval with the sum of numbers in it;

if the resulting array is different from the initial one, return to step 1, otherwise return the result.

Input

A non-empty integer array such that:

 

-10000 ≤ arr[i] ≤ 10000

1 ≤ arr.length ≤ 1000

Output

An integer array.

 

Examples

For arr = [1, 2, 3, 5, 6, 4, 2, 3] the result should be [21, 5]:

 

[1, 2, 3, 5, 6, 4, 2, 3] --> [(1), (2 + 3 + 5), (6 + 4), (2 + 3)] --> [1, 10, 10, 5]

[1, 10, 10, 5] --> [(1 + 10 + 10), (5)] --> [21, 5]

For arr = [-3, 4, 5, 2, 0, -10] the result should be [1, 7, -10]:

 

[-3, 4, 5, 2, 0, -10] --> [(-3 + 4), (5 + 2), (0 + -10)] --> [1, 7, -10]
