Multiple of 5

You are given 

N inputs. Print the given inputs until you encounter a multiple of 5.

Input

The first line of input is an integer 

N. The next N lines each contain an integer as input.

Explanation

In the given example, there are 

6 inputs. 1, 2, 3, 5, 9, 6

After 

3, we have encountered 5, which is a multiple of 5.

So, the output should be

Armstrong numbers between two intervals

Write a program to print all the Armstrong numbers in the given range 

A to B(including A and B). An N-digit number is an Armstrong number if the number equals the sum of the Nth power of its digits.

Input

The first line has an integer 

A. The second line has an integer B.

Output

Print all Armstrong numbers separated by a space.
If there are no Armstrong numbers in the given range, print 

-1.

Explanation

For 

A = 150 and B = 200

For example, if we take number 153, the sum of the cube of digits 

1, 5, 3 is

 13 + 53 + 33 = 153.

So, the output should be 

153.

Sample Input 1
150
200
Sample Output 1
153
Sample Input 2

Pyramid

Given an integer 

N, write a program to print a pyramid of N rows as shown below.

Input

The first line of input is an integer 

N.

Explanation

In the example, the number of rows in the pyramid is 

5.

So, the output should be

. . . . 0 . . . . 
. . . 0 0 0 . . .

Draw a class diagram and use case diagram for suppliers of building construction . Write down all the methodclass.

example: getname()

The four branches of a bakery in new York made sales(in millions us dollars). As shown below

A 1.13 1.71 1.39 1.68 1.74 1.19 1.15 1.36

B 1.34 1.47 1.74 1.53 1.74 1.19 1.15 1.36

C 1.15 1.33 1.01 1.28 1.20 1.59 1.59 1.68

Write a well commented program in R that uses the data to compute the following parameter estimates

a) CS =(( (n₁-1)s²₁ +(n₂-1)s₂² +(n₃-1)s²₃ +(n₄-1)s²₄)/(n₁+n₂+n₃+n₄-4))^1/2

b)CM= (n₁x₁+n₂x₂+n₃x₃+n₄x₄)/(n₁+n₂+n₃+n₄)

where

n_i =sample size for the i^th branch

x_i =sample mean for the i^th branch

s²_i=sample variance for the i^th branch

i=1,2,3,4
