Your task is write a program to identify the input chord.

Input

The first line of input contains the integer T (1 ≤ T ≤ 10), the number of test cases.
Each case starts with an integer N (5 ≤ N ≤11), the number of strings are needed to form a chord. Next N lines will contain N strings
and these will form a chord.

Output

You program should output exactly T lines. Identify the input chord and print it. Each line should be the form of 'Case X: Chord' , where 'X' is the case number and 'Chord' is the name of the chord.
