An expression is a string consisting of three characters, where the first and the last characters are digits (from $0$ to $9$), and the middle character is a comparison symbol (<, = or >).

An expression is true if the comparison symbol matches the digits (for example, if the first digit is strictly less than the last digit, the comparison symbol should be <).

For example, the expressions 1<3, 4>2, 0=0 are true, while 5>5, 7<3 are not.

You are given a string $s$, which is an expression. Change as few characters as possible so that $s$ becomes a true expression. Note that if $s$ is already true, you should leave it as it is.

Input

The first line contains one integer $t$ ($1 \le t \le 300$) — the number of test cases.

Each test case consists of one line containing the string $s$ ($|s| = 3$, the first and the last characters of $s$ are digits, the second character is a comparison symbol).

Output

For each test case, print a string consisting of $3$ characters — a true expression which can be obtained by changing as few characters as possible in $s$. If there are multiple answers, print any of them.
