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

Write an if-else statement that compares the age variable with the value 65. If age is greater than or equal to 65, add 1 to senior_citizens. Otherwise, add 1 to non_seniors.

Given a student has scored

M marks in Maths, P marks in Physics and C marks in Chemistry. Write a program to check if a student is eligible for admission in a professional course based on the following criteria:Sum of marks in any two subjects >= 100 and M + P + C >= 180.

Create a program in Python to accept input from a student and then display if the student is eligible to graduate and if so if they will graduate cum laude, magna cum laude or summa cum laude.  

Your program should prompt the student to enter his/her name and gpa. If the gpa is 4.0, then display a message stating that he/she has graduated summa cum laude. If the gpa is less than 4.0 but greater than or equal to 3.8, then display a message that they have graduated magna cum laude. If the gpa is not greater than or equal to 3.8 but greater than or equal to 3.5, then display a message that they have graduated cum laude. If the gpa is less than 3.5 but greater than 2.0, display a message that they have graduated. If the gpa is less than 2.0, display a message that they are not eligible to graduate but can take more courses to bring their gpa up to at least 2.0.
