Difficulty—

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: $A$ $B$ [samples]

Samples

Input #1

229 390

Output #1

Hard

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

Input #2

123456789 9876543210

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.
