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.

Constraints

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

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.

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.
