Comparison Operators

The comparison operators in the C language are shown in the table below.

Each operator compares its two operands (the left value and the right value) and returns true (1) if the comparison holds or false (0) otherwise. For example, 2 > 3 returns false (because 2 is less than 3), 3 != 4 returns true, and 3 >= 3 returns true.

Given several C comparison expressions, write a program that computes the result of each one.

The input consists of at most 12000 lines. Each line contains two integers a and b separated by a single comparison operator, which is one of >, >=, <, <=, ==, !=. There is exactly one space between the operator and each operand. When a line whose operator is E is reached, stop reading and terminate the program. ($-10000 \le a, b \le 10000$)

For each input expression, print its result on its own line, in order. For the $N$-th expression print it in the form Case N: true or Case N: false, where $N$ is the 1-based index of the expression; print true if the comparison holds and false otherwise. (The terminating E line is not counted.)
