【例68.3】 忽略大小写的字符串比较

Description

Sometimes when comparing strings, we want to ignore the case of letters. For example, "Hello" and "hello" are considered equal when ignoring letter case. Please write a program to compare two strings while ignoring letter case.

Input Format

The input consists of two lines, each containing one string (each string is less than 8080 characters long and contains only uppercase and lowercase letters).

Output Format

If the first string is less than the second string, output a single character "<<";
If the first string is greater than the second string, output a single character ">>";
If the two strings are equal, output a single character "==".

Sample

Hellohowareyou
helloHowareyou
=
