Divisibility Checking

Given two integers a and b, determine whether a is divisible by b. In other words, check if the remainder when a is divided by b is zero. Formally, a is divisible by b if and only if \(a \mod b = 0\).

The program should read the input from standard input (stdin) and write the output to standard output (stdout). The output should be the string "divisible" if a is divisible by b, otherwise it should output "not divisible".

inputFormat

The input consists of two space-separated integers a and b provided in a single line from stdin. It is guaranteed that b is non-zero.

outputFormat

Output a single line from stdout containing the string "divisible" if a is divisible by b, otherwise output "not divisible".
