#35Event Badge Generator
An event management system generates attendee badges using a limited collection of printed letter cards. You are given two strings: badgeName — the name that needs to be printed on an attendee's badge. letterStock — the letters currently available for printing.
Determine whether badgeName can be created using the letters from letterStock. Each letter in letterStock can be used at most once. If a letter appears multiple times in badgeName, the required number of copies must be available in letterStock. Return true if the complete badge name can be generated; otherwise, return false.
