Diamond Crystal

Given an integer value

N, write a program to print a diamond pattern of 2*N rows as shown below.

You are given a word W as input. Print W by adding a hyphen (-) between each letter in the word.

Explanation

In the given example, the word is

Hello.So, the output should be H-e-l-l-o.

Zig-Zag Order in Matrix

you are given a matrix of dimensions M * N . print the numbers of the matrix in the zig-zag order.

Zig-Zag order of the matrix.

start from the first element in the first row of the matrix and print all the numbers in the first row.

after reaching the end of the first row , move to the last element in the next row and start printing the numbers from the right side of the second line until you reach the first element in the second line .

Now jump to the first element in the third row and repeat the above process.

Sample input:

4 4

1 2 3 4

5 6 7 8

9 10 11 12

13 14 15 16

SAMPLE OUTPUT :

1 2 3 4 8 7 6 5 9 10 11 12 16 15 14 13

SAMPLE INPUT:

3 4

1 2 3 4

10 11 12 5

9 8 7 6

SAMPLE OUTPUT :

1 2 3 4 5 12 11 10 9 8 7 6

Maximum:

You are given N number of inputs. Print the maximum of them after each input.

Input

The first line of input is an integer N. The next N lines each contain an integer as input.

Explanation

In the example, you are given

6 inputs 1, 0, 3, 2, 9, 8.

1 is maximum in the input 1.

1 is maximum in the input 1, 0.

3 is maximum in the input 1, 0, 3.

3 is maximum in the input 1, 0, 3, 2.

9 is maximum in the input 1, 0, 3, 2, 9.

9 is maximum in the input 1, 0, 3, 2, 9, 8.

So, the output should be

Hyphenate Letters:

You are given a word W as input. Print W by adding a hyphen (-) between each letter in the word.

Input

The first line of input is a string W.

Explanation

In the given example, the word is Hello.

So, the output should be

H-e-l-l-o.

Sample Input 1

Hello

Sample Output 1

H-e-l-l-o

Sample Input 2

Everyone

Sample Output 2

Last half of List:

You are given an integer N as input. Write a program to read N inputs and print a list containing the elements in the last half of the list.

Input:

The first line of input is an integer N. The second line contains N space-separated integers.

Explanation

Sample Output 1

In the example, we are given

6 numbers 1, 2, 3, 4, 5, 6 as input.

The last half of elements of the list are 4, 5, 6. So, the output should be [4, 5, 6].

Sample Output 2

In the example, we are given

5 numbers 1, 11, 13, 21, 19 as input. The last half of elements of the list are 21, 19. So, the output should be [21, 19].

Sample Input 1

6

1 2 3 4 5 6

Sample Output 1

[4, 5, 6]

Sample Input 2

5

1 11 13 21 19

Sample Output 2

[21, 19]
