Albert Einstein teaches a business class at Podunk University. To evaluate the students in this class, she has given four tests. It is now the end of the semester and Alberta would like to have a program that inputs each student’s test scores and outputs the average score for each student and the overall class average. (Hint: The outer loop should allow for Ms. Einstein to input all the students, one by one, and the inner loop should accept the four exam scores and compute the average for each student

4. The Positive Ones

by CodeChum Admin

There are different kinds of numbers, but among them all, the most commonly used numbers in our daily lives are those positive ones. So, I only want you to count all the positive numbers from the 4 outputted values and print out the result.

Go and search for the positive ones among these four!

Input

A line containing four numbers (may contain decimal places) separated by a space.

2·-4·3.6·1

Output

A line containing an integer.

write a program to print the first prime number in the given inputs .

Rotate Matrix Rings

Given a matrix of order M*N and a value K, write a program to rotate each ring of the matrix clockwise by K elements. If in any ring has less than or equal to K elements, then don’t rotate that ring.

Input

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

The next M lines will contain N space-separated integers.

The next line will contain an integer, denoting K.

Output

The output should be M*N matrix by rotating the matrix by K elements.

Explanation

Therefore, by rotating each ring in clockwise direction by 3 elements will give (13, 9, 5, 1, 2, 3, 4, 8, 12, 16, 15, 14) and (10, 6, 7, 11). So the output should be
