FARIDA - Princess Farida


Once upon time there was a cute princess called Farida living in a castle with her father, mother and uncle. On the way to the castle there lived many monsters. Each one of them had some gold coins. Although they are monsters they will not hurt. Instead they will give you the gold coins, but if and only if you didn't take any coins from the monster directly before the current one. To marry princess Farida you have to pass all the monsters and collect as many coins as possible. Given the number of gold coins each monster has, calculate the maximum number of coins you can collect on your way to the castle.

Input

The first line of input contains the number of test cases. Each test case starts with a number N, the number of monsters, 0 <= N <= 10^4. The next line will have N numbers, number of coins each monster has, 0 <= The number of coins with each monster <= 10^9. Monsters described in the order they are encountered on the way to the castle.

Output

For each test case print “Case C: X” without quotes. C is the case number, starting with 1. X is the maximum number of coins you can collect.

Example

Input:
2
5
1 2 3 4 5
1
10

Output:
Case 1: 9
Case 2: 10

the case with N = 0 caused me two WA.So be careful with it...

costed me 2 WAs since i didnt output "Case ".... :p

This one is hard for me. I have no idea how to do it.

N = 0 input seems to be stupid to me.
Costed 1 WA :(

Why ? Why ? Why is my fast i-o not working in this question. I get a WA each time I use fast i-o and AC only when I use scanf !

WTH SPOJ!!! NZEC with Python instantaneously. AC with C++. Why can't problem posters sanitize test case files before putting up questions? Clearly stray line endings/white space is causing NZEC in Python at 0.00 time.

@Shashank Tiwari....Thanks! This case fetched me multiple wrong answers....

For all those who are using printf to print the output , check if this is printing correct for n=0.

1
0

Output should be 0. If anything else is getting printed check the format specifier. Dont use %lld to print 0 . Instead use 0LL . Mismatch of format specifier is undefined behaviour in gcc C. 0 is by defualt considered to be %d type.

Hope this solves the dilemma of why printf getting wrong answer in this question.
