Input a positive integer N and return a minimum positive integer m (M is at least two digits), so that the product of M is equal to N, for example, input 36, output 49, input 100, output 455, if a certain N does not have such M, return-1. Package

This question is amazing. Wa has made four rounds... Damn it, C ++ won't be used, and the output should be output as is... For example: 0000000000000000006*000000000000001 The output is 0000000000000000006*000000000000001. Instead of 6*1 Import Java.
