문제

C언어의 비교 연산자는 아래 표에 나와있다. 

연산자
> 크다
>= 크거나 같다
< 작다
<= 작거나 같다
== 같다
!= 같지 않다

이 연산자는 두 피연산자를 비교하고, (왼쪽 값과 오른쪽 값) true또는 false (1 또는 0)을 리턴한다. 예를 들어, 2 > 3은 "false"를 리턴하고 (2는 3보다 작기 때문), 3 != 4는 "true", 3 >= 3은 "true"를 리턴한다.

C언어의 비교 연산식이 주어졌을 때, 결과를 구하는 프로그램을 작성하시오.

입력

입력은 최대 12000줄로 이루어져 있다. 각 줄은 두 정수 a, b가 주어지며, 정수 사이에는 연산자 ">", ">=", "<", "<=", "==", "!="중 하나가 주어진다. 연산자와 피연산자 사이에는 공백이 하나 있으며, 연산자로 "E"가 주어진 경우에는 프로그램을 끝낸다. (-10000 ≤ a,b ≤ 10000)

출력

입력의 각 줄 마다 입력으로 주어진 식의 결과가 "true"인지 "false"인지 출력한다.

예제 입력 1

3 != 3
4 < 4
4 <= 5
3 E 3

예제 출력 1

Case 1: false
Case 2: false
Case 3: true
