Problem Description:

Banta and his friends decide to play a game with names. They meet together and cut out alphabetical letters from a piece of waste cardboard which spell some names. After getting bored by playing for some time, they hang the letters of some two names above the main entrance of Banta's House. That night, when everyone went to bed, someone took all the letters of the hung names and he/she may have shuffled the letters and put them in one pile in front of the door.

The next morning it was impossible to find the culprit who had made the disorder. But everybody wondered whether it is possible to restore the names from the letters lying at the door? That is, we need to verify that there are no extra letters, and that nobody will need to cut more letters.

Help Banta and his friends to cope with this problem. You are given both names that hung over the front door the previous night, and a pile of letters that were found at the front door next morning.

Input
The input file consists of three lines: the first line contains the first name, The second line contains the second name and the third line contains letters in a pile that were found at the door in the morning. All lines are not empty and contain only uppercase Latin letters.

Output
Print "YES" without the quotes, if the letters in the pile could be permuted to make the names of the "New Year and Christmas Men". Otherwise, print "NO" without the quotes.

Constraints
The length of each line does not exceed 100.

Example
Input:
SANTACLAUS
DEDMOROZ
SANTAMOROZDEDCLAUS

Output:
YES
Input:
PAPAINOEL
JOULUPUKKI
