TIPTOP - Tip Top Game

Problem Statement:

Alim and sufian are two good friends. They loves to playing game with number recently they discover a new game name “Tip Top”. The rule of the game is they took a number (N) randomly after that they find the all divisors of N. Then they starting to play the game first alim took a divisor, then sufian so on. The person who took the last divisor will win the game.

Every time the game started with alim . Now alim wants to know when he will win.

As you a good programmer your task is to find will alim win or not.



Input starts with an integer T ( T ≤ 10), denoting the number of test cases. Each case starts with a line containing an integer N ( 1 N 1018 ) the number.


For each case you have to print “Yes” if alim will win otherwise “No” with case number. See the sample input/output for exact formatting.

Sample Input/Output:

Sample Output


 Case 1: Yes
 Case 2: No

No need to calculate all the divisor!!
think clever :)

[EDITED with answers]

Could someone clarify the statement please?
1. What does 'taking' a divisor mean? --- consider it as removing it from the list of divisors.
2. Do 'divisor's include 1 and the number itself as well? --- yes.
3. Are they playing optimally? (I hope so) --- This isn't a dp question. There is only one way to play - choose any divisor and remove it from the list.

take :-> unsigned long long s=sqrt(n);
it won't accept integer value

long long,space,\n costed me 3 WA -_-

WA in 4.3.2 and AC in 14. why so?

if(sqrt(n)==floor(sqrt(n))) gives wrong ans.
if(x*x == n) gets accepted.

Use sqrtl() for large integers square root.

Interesting problem to tackle. Would have been a very frustrating, non-learning experience if I didn't turn to comments.

345678 -> No
