DIVSUM - Divisor Summation

Given a natural number n (1 <= n <= 500000), please output the summation of all its proper divisors.

Definition: A proper divisor of a natural number is the divisor that is strictly less than the number.

e.g. number 20 has 5 proper divisors: 1, 2, 4, 5, 10, and the divisor summation is: 1 + 2 + 4 + 5 + 10 = 22.

Input

An integer stating the number of test cases (equal to about 200000), and that many lines follow, each containing one integer between 1 and 500000 inclusive.

Output

One integer each line: the divisor summation of the integer given respectively.

Example

Sample Input:
3
2
10
20

Sample Output:
1
8
22

Warning: large Input/Output data, be careful with certain languages

For those who are getting WA, take care of the square no.'s.That is no's such as 16.

For n=1, answer should be 0. Cost me 1 WA!! Got AC finally!

Hello everybody, Could anybody explain me why runtime error is occuring in my judge, (I have tested the program on my c++ compiler , the answer is being correcly for every case also 1)

Can anyone give me a test with O(log n)?

I don't know why i am getting wrong answer. I expected a TLE but definitely not a WA.

@Anchrondite answer for input 1 must be zero its because we need to consider proper divisors that are less than the given number so for number only divisor is 1 but it is not a proper divisor as it is not less than 1 i hope u got.
