Kalinjar Fort is a popular tourist place in Bundelkhand, Utter Pradesh. Everyday peoples registered to visit Fort as token provided based on first come basis. Everyday limited numbers of peoples are allowed to visit. The management selects a number N1 randomly every day and generates another number N2 as count of the total number of set bits (i.e., total no. of 1^s) in binary representation of all numbers from 1 to N1. For example, N1=3 then N2=4 [1(01) +2(10) +3(11)]. So, write a python module CountBit.py to find N2 using N1. You need to import this module , define a function Get_Token(n) which takes a number and return value as shown in example by calling the appropriate function implemented in CountBit.py module.

Given a string of numbers S, the task is to find the maximum value from the string S, you can add a ‘+’ or ‘*’ sign between any two numbers.

For example, S=891. As 8*9*1 = 72 and 8*9+1 = 73. So, 73 is maximum.

Write a python module MaxValue.py for solve the above task. You need to import this module ,define a function Find_Max(n) which takes a string and return maximum value or error message as shown in example by calling the appropriate function implemented in MaxValue.py module. Also handle the possible exceptions and display the exception message in form of string.

Ordered Matrix

Given a M x N matrix, write a program to print the matrix after ordering all the elements of the matrix in increasing order.

Input

The first line of input will contain two space-separated integers, denoting the M and N.

The next M following lines will contain N space-separated integers, denoting the elements of each list.

Output

The output should be M lines containing the ordered matrix.

Note: There is a space at the end of each line.

Explanation

For example, if the given M is 3 and N is 3, read the inputs in the next three lines if the numbers given in the next three lines are the following.

1 20 3

30 10 2

5 11 15

By ordering all the elements of the matrix in increasing order, the ordered matrix should be

Friend and Enemy

A group of F friends went to a haunted house.Each member was given a shirt with a number on it ranging from 1 to F. As they entered the haunted house, one of them was kidnapped and an enemy joined them.But unfortunately, the enemy didn't wear the shirt with the same number as the kidnapped one, instead wore the same as some other person.Find the numbers on the shirts of the enemy and the kidnapped person.

Input

The input is a single line containing space-separated positive integers from 1 to F.

Output

The output should be a single line containing the shirt numbers of the enemy and kidnapped person separated by a space.

Explanation

The given array is 3 1 5 2 1

In the range from 1 to 5, the number 1 has occured twice and 4 is the missing number. So, 1 belongs to the enemy's shirt, and 4 belongs to kidnapped.Hence, the output should be 1 4.
