Boltu and Balti are two friends. Boltu is a great programmer whereas Balti is a newbie programmer. But Balti thinks that he is also a great programmer, but Boltu can’t accept Balti as a great programmer. Now Boltu challenges Balti to solve a task to prove himself as a great programmer. Balti accepts that challenge. The task is Boltu will give him a number N. Balti have to say if N-th Partial sum number and N-th factorial number are same or not. Balti knows the meaning of **N-th partial sum is summation from 1 to N (1+2+....+N)** and the meaning of **N-th factorial is multiplication of all numbers from 1 to N (1*2*....*N)**. Balti is getting stuck to find the solution. Now he wants your help. Help him to win this challenge by solving this problem. Input: ------ Input starts with an integer T (1 <= T <= 100) denoting the number of test cases. Each case contains an integer N (1 ≤ N ≤ 10000000). Output: ------- For each test case, print "`Case X-> Y;`". Where X denotes the number of test case. **If N-th Partial sum and N-th factorial number are same** then Y will "YES", if these are not same then Y will "NO", Sample Input ------------ 2 4 5 Sample Output ------------- Case 1-> NO; Case 2-> NO;
