A. k-roundingtime limit per test1 secondmemory limit per test256 megabytesinputstandard inputoutputstandard outputFor a given positive integer n denote its k-rounding as the minimum positive integer x, such that x ends with k or more zeros in base 10 and is divisible by n.For example, 4-rounding of 375 is 375·80 = 30000. 30000 is the minimum integer such that it ends with 4 or more zeros and is divisible by 375.Write a program that will perform the k-rounding of n.InputThe only line contains two integers n and k (1 ≤ n ≤ 109, 0 ≤ k ≤ 8).OutputPrint the k-rounding of n.ExamplesInput375 4Output30000Input10000 1Output10000Input38101 0Output38101Input123456789 8Output12345678900000000
