Read from standard input two character set (does not contain Spaces, tabs, carriage returns, such as white space characters), the characters in a character set disorder, and there may be repeated characters, characters are exactly the same as the two character sets (characters are the same, if repeat, repeat the same number, the order is not necessarily the same), the two character set is the same, write a program to judge the input of the two character sets are the same: use 1 is the same, with 0 means different,
