Business Card Distribution

# Introduction In this challenge, we will help Bob determine the number of ways she can distribute her different business cards to fairies. Bob can give any number of business cards to one or more fairies, and the same card given to different fairies is considered the same choice. We need to calculate the number of possible methods taking into account the large number of possible combinations, and return the result modulo 1314520.
