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.
