信件AI (CI翻译)
Vasya decided to write an anonymous letter cutting the letters out of a newspaper heading. He knows heading $*s*_{1}$ and text $*s*_{2}$ that he wants to send. Vasya can use every single heading letter no more than once. Vasya doesn't have to cut the spaces out of the heading — he just leaves some blank space to mark them. Help him; find out if he will manage to compose the needed text.
