Problem Statement

You are given positive integers A and B.
Let us calculate A+B (in decimal). If it does not involve a carry, print Easy; if it does, print Hard.

Input

Input is given from Standard Input in the following format:
A B

Output

If the calculation does not involve a carry, print Easy; if it does, print Hard.

Constraints

• A and B are integers.
• $1 \le A,B \le 10^{18}$

Sample Input 1

229 390

Sample Output 1

Hard

When calculating 229+390, we have a carry from the tens digit to the hundreds digit, so the answer is Hard.

Sample Input 2

123456789 9876543210

Sample Output 2

Easy

We do not have a carry here; the answer is Easy.
Note that the input may not fit into a 32-bit integer.
