The Magic HackerEarth Nirvana solutions Hiring Challenge

February 25, 2015 by Dhaval Dave

Navi got a task at school to collect N stones. Each day he can collect only one stone. As N can be a very large number so it could take many days to complete the task,
but then he remembers that his mother gave him a magic that can double anything (i.e if he has 2 stones, the magic will make them to 4 stones). Navi can use this magic any number of time on the collected stone on a particular day and add this to the previously collected stones. Remember that he wants exactly N stones and he can’t throw any stone. If he gets more than N stones then he gets 0 marks, of course he doesn’t want 0 marks. Help him to collect exactly N stones in minimum number of days.

Input

First line of input will contain number of test cases (T). Then next T lines contains a single number N, which is number of stones Navi has to collect.

Output

For each test case, Print a single number which is the minimum number of days taken by Navi to complete the task.

Constraints

1 <= T <= 10^5
0 <= N <= 10^9

Sample Input (Plaintext Link)

2
1
3
Sample Output (Plaintext Link)
1
2
Explanation : 
When N = 1, in 1 day he can collect stone.
When N = 3, on 1st day he collect 1 stone, make it double. so now he has 2.
On day 2, he can collect one , so total now he has collected 3 stones in 2 days.
 
Code Solution : 
 
#include <stdio.h>

int main(){
int T,N,stone,remaining,day;
scanf("%d",&T);
while(T--)
{
scanf("%d",&N);
day=1;
remaining=N;
    while(1)
    {
        if(remaining==1) 
        break;
        if(remaining==0)
        {day--; break;}
        stone=1;
        while( (stone*2) <= remaining){
            stone = 2*stone;
        }
    remaining = remaining - stone;
    day++;
    }
printf("%dn",day);
}

return 0;
}
