We define b is a Divisor of a number a if a is divisible by b. So, the divisors of 12 are 1, 2, 3, 4, 6, 12. So, 12 has 6 divisors.
Now you have to order all the integers from 1 to 1000. x will come before y if
1) number of divisors of x is less than number of divisors of y
2) number of divisors of x is equal to number of divisors of y and x > y.
Input
Input starts with an integer T (≤ 1005), denoting the number of test cases.
Each case contains an integer n (1 ≤ n ≤ 1000).
Output
For each case, print the case number and the nth number after ordering.
Sample Input | Output for Sample Input |
5 1 2 3 4 1000 | Case 1: 1 Case 2: 997 Case 3: 991 Case 4: 983 Case 5: 840 |
