Difficult Addition
Arjun is trying to add two numbers. Since he has learned addition recently, an addition which requires a carry is difficult for him. Your task is to print Easy if the addition does not involve a carry, Otherwise print Hard.
Input
The first line of input contains two space separated integers A and B.
Output
If the addition does not involve a carry,print Easy, otherwise print Hard.
Explanation
When calculating 229 + 390, we have a carry from the tens digit to the hundreds digit, so the answer is Hard.
Sample Input1
229 390
Sample Output1
Hard
Sample Input2
123456789 9876543218
Sample Output2

String Concatenation
Disha has three strings A, B, and C consisting of lowercase letters.She also has a string T consisting only of characters 1, 2 and 3.
She wants to concatenate the three strings according to the characters in T.
Your task is to print the final output string.
Note: Formally, follow the below instructions:
* For each integer i such that 1<=i<=|T|, let the string si be defined as follows:
- A if Ti = 1.
- B if Ti = 2.
- C if Ti = 3.
*Concatenate the strings s1,s2,...,s|T| in this order and print the resulting string.

Find the Password
Joey is playing escape room and to exit the room he has to find the password for the final door.To know the password he is given a sentence G and told to rearrange the sentence by rotating its W words in the right.Can you help joey find the password?
Input
The first line of input is a string G.
The second line of input is an integer W.
Output
The output is a string contains a sentence got by the rearrangement as per above mentioned criteria.
Explanation
In the above example, the sentence is Raju is going to school and W is 3.
Shift the three words in the right,which means the last three words will be moved to the front.
So, the output should be going to school Raju is
Sample Input1
Raju is going to school
3
Sample Output1
going to school Raju is
Product of the String
You are given an alphanumeric string S.Write a program to multiply all the charcters(except trailing zeroes) in S and print the output.
Rules for multiplication:
- If the character is digit, multiply its value.
- If the character is an alphabetic character, multiply the product of digits of its ASCII value.
Input
The first line contains a string S.
Output
The output should be a integer denoting the product of characters.
Explanation
For N = 123a4
ASCII value of a is 97.
Product of digits of ASCII value of a is 9 *7 = 63.
Therefore the product of characters is 1*2*3*4*63*4 = 1512.
Sample Input1
123a4
Sample Output1
1512
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

Input
The first line of input contains space-separated integers.
Output
Each line of output should contain the height of the pyramid and its frequency in the ascending order of the pyramid's height.
Explanation
In the example, The given pyramid heights are 1,5,1,2,5,6.
The frequency of each unique pyramid height is
1 2
2 1
5 2
6 1
Sample Input1
