You are encouraged to solve this task according to the task description, using any language you may know.
Start a value at 1024. Loop while it is greater than 0. Print the value (with a newline) and divide it by two each time through the loop.
Ada
<ada> declare
I : Integer := 1024;
begin
while I > 0 loop Put_Line(Integer'Image(I)); I := I / 2; end loop;
end; </ada>
BASIC
<qbasic>i = 1024 while i > 0
print i i = i / 2
wend</qbasic>
C
int i = 1024; while(i > 0) { printf("%d\n", i); i /= 2; }
Forth
: halving ( n -- ) begin dup 0 > while cr dup . 2/ repeat drop ; 1024 halving
Java
<java>int i = 1024; while(i > 0){
System.out.println(i); i >>= 1; //also acceptable: i /= 2;
}</java>
JavaScript
var n = 1024; while (n>0) { print(n); n/=2; }
Logo
make "n 1024 while [:n > 0] [print :n make "n :n / 2]
