You are given two very long integers a, b (leading zeroes are allowed). You should check what number a or b is greater or determine that they are equal. The input size is very large so don't use the reading of symbols one by one. Instead of that use the reading of a whole line or token. As inputoutput can reach huge size it is recommended to use fast inputoutput methods: for example, prefer to use scanfprintf instead of cincout in C++, prefer to use BufferedReaderPrintWriter instead of ScannerSystem.out in Java. Don't use the function input() in Python2 instead of it use the function raw_input().

输入描述:

The first line contains a non-negative integer a.The second line contains a non-negative integer b.The numbers a, b may contain leading zeroes. Each of them contains no more than 106 digits.

输出描述:

Print the symbol "" if a b and the symbol "" if a b. If the numbers are equal print the symbol "=".
