Given an M X N integer matrix, write a program to

-Find all zeros and replace them with the sum of their neighboring elements

-After replacing the zeros, set all other elements in the corresponding row and column with zeros

(excluding the elements which we previously zeros)

Note: consider the upper, lower, right and left elements as neighboring elements

Input

The first line of input is two space-separated M and N

The next M lines of input contain N space-separated integers

Output

The output should be an M X N matrix

SampleInput1:

3 3

1 2 3

4 0 2

1 1 8

Sample Output1:

1 0 3

0 9 0

0 0 22 0 0

5 5 0 0 0

7 4 0 0 0

You are given a list of prices, where price [ i ] is the price of a given stock on the i th day

Write a program to print the maximum profit by choosing a single day to buy a stock and choosing a different day in the future to sell that stock

If there is no profit that can be achived return 0

Input:

The input is a single line containing space - separated integers

output:

The output should be a an integer

sample Input1:

7 1 5 3 6 4

sampleoutput1:

5

sampleinput2:

1 11 13 21 19

sample output2:

20

Write a program

Input: 5,3,3; Output: 5,15,45

Given a space-separted list of integers as input, write a program to add the elements in the given range and print their sum

You will be given M multiple range queries,where

You should print the sum of numbers that belong to the corresponding range

note: while checking if the number belongs to a range,including the string and numbers of range as well

Input

The first line of input is space-separated integers

The secondline of input is a positive integers M denoting the number of queries

The next M line contain two space-separated integer

Output:

The output should be M line printing the sum of each includes range

sample input 1:

1 2 2 3 3 3 4 5 6

Given a word W as input, write a program to print the unique character in the word, in the order of their occurrence

Note: consider lower and upper case letters as different

Input

The input is a single line containing as word W

Output:

The out should be a single line containing space- separated character

sample input: MATHEMATICS

sample Output: M A T H E I C S
