Consider an arbitrary sequence of integers. One can place + or - operators between integers in the sequence, thus deriving different arithmetical expressions that evaluate to different values. Let us, for example, take the sequence: 17, 5, -21, 15. There are eight possible expressions:
17 | + | 5 | + | -21 | + | 15 | = | 16 |
17 | + | 5 | + | -21 | - | 15 | = | -14 |
17 | + | 5 | - | -21 | + | 15 | = | 58 |
17 | + | 5 | - | -21 | - | 15 | = | 28 |
17 | - | 5 | + | -21 | + | 15 | = | 6 |
17 | - | 5 | + | -21 | - | 15 | = | -24 |
17 | - | 5 | - | -21 | + | 15 | = | 48 |
17 | - | 5 | - | -21 | - | 15 | = | 18 |
You are to write a program that will determine divisibility of sequence of integers.
The second line contains a sequence of N integers separated by spaces. Each integer is not greater than 10000 by it's absolute value.
Write to the output file the word "Divisible" if given sequence of integers is divisible by K or "Not divisible" if it's not.
