program1:

public class Beat
{
public static void main(String args[])
{

int beat=1024;
int count=0;
while(beat>1)
{
beat=beat/2;
count=count+1;
}
System.out.println("total counts:" +count);
}
}

output=>total counts:10

program2:

public class Flower
{
public static void main(String args[])
{

int flower=1;
int count=1;
while(count<=7)
{
flower=flower*2;
count=count+1;
}
System.out.println("total flowers" +flower);
}
}

output=> total flowers:128
