Adding elements to an array

say I have an array

x=[0,0,2,3,4]

and a code

for n=1
    if (10^n)*p<q
        n=n+1;
    elseif (10^n)*p>q
        break
    end
end

is there a way to add an extra 0 to the start of x if my n value goes up. for example. If n is one x=[0,0,2,3,4] and if n is 2 x=[0,0,0,2,3,4] and if n=3 x=[0,0,0,0,2,3,4] and so on. Thanks for the help.
