I was trying to solve problem '1234 - Harmonic Number', I wrote the following code

long long H( int n ) {

long long res = 0;

for( int i = 1; i <= n; i++ )
res
= res + n / i;

return res;
}

Yes, my error was that I was using the integer divisions only. However, you are given n, you have to find H(n) as in my code.

# Input

Input starts with an integer T (≤ 1000), denoting the number of test cases.

Each case starts with a line containing an integer n (1 ≤ n < 231).

# Output

For each case, print the case number and H(n) calculated by the code.

# Output for Sample Input
