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.
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).
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.
53<73>78=90=05<3
3<7 8>7 8<9 0=0 0<3
