ACM Contest Topic "C + + large number multiplication"

Topics :

      When a large number is multiplied, it is time consuming memory to use the traditional method to calculate directly, so we can use the method of simulating arithmetic to Calculation.

Ideas :

Analog Phase multiplication

For example :

123*789=97047

The process of simulating operations:
