Hard Calculation

题目描述

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 $Hard$.

输入格式

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

输出格式

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

229 390

Hard

123456789 9876543210

Easy

提示

$A$ and $B$ are integers. $1 \le A,B \le 10^{18}$When calculating $229+390$, we have a carry from the tens digit to the hundreds digit, so the answer is $Hard$.
We do not have a carry here; the answer is $Easy$.
Note that the input may not fit into a $32$-bit integer.
