Mirko is a great codebreaker. He knows any cipher in the world can be broken by frequency analysis. He has completely the wrong idea what frequency analysis is, however.
He intercepted an enemy message. The message consists of numbers, smaller than or equal to
.
Mirko believes frequency analysis consists of sorting this sequence so that more frequent numbers appear
before less frequent ones.
Formally, the sequence must be sorted so that given any two numbers and
,
appears before
if
the number of times
appears in the original sequence is larger than the number of time
does. If the
number of appearances is equal, the number whose value appears sooner in the input should appear
sooner in the sorted sequence.
Help Mirko by creating a "frequency sorter".
Input Specification
First line of input contains two integers,
, length of message, and
, the number from task description.
Next line contains integers smaller than or equal to
, the message itself.
Output Specification
First and only line of output should contain numbers, the sorted sequence.
