remove zero padding for binary vector and string

case 1

a=[1 0 0 1 0 1 1 1 1 1 0 0 1 0 1 0 0 1 0 0 0 0 0 1 1 1 1 1 1 0 1 0 1 0 1 0 1 0 1 0 0 0 1 1 1 0 0 0 0 0 0 0 0];
d=[1 0 1 0 1 0 1 1 0 0 1 1 0 1 1 1 0 1 1 0 1 0 0 1 0 0 1 1 1 0 0 0 1 0 1 1 1 1 0 0 1 0 1 0 0 0 1 1 0 0 0 0 1 0 0 0 0 0 1 1 1 1 1]
q=zeros(1,length(d)-length(a))
w=[a q]

case 2

x = input('x: ','s') 
y = input('y: ','s')
nx = length(x)
ny = length(y)
if ny > nx
  sprintf(sprintf('%%0%is',ny),x)
elseif nx > ny
  sprintf(sprintf('%%0%is',nx),y)
else
  display('nx=ny')
end

how to remove zero padding for case 1 and case 2? can anyone help me?

case 1

a=[1 0 0 1 0 1 1 1 1 1 0 0 1 0 1 0 0 1 0 0 0 0 0 1 1 1 1 1 1 0 1 0 1 0 1 0 1 0 1 0 0 0 1 1 1 0 0 0 0 0 0 0 0];
d=[1 0 1 0 1 0 1 1 0 0 1 1 0 1 1 1 0 1 1 0 1 0 0 1 0 0 1 1 1 0 0 0 1 0 1 1 1 1 0 0 1 0 1 0 0 0 1 1 0 0 0 0 1 0 0 0 0 0 1 1 1 1 1];
w=a;

case 2

Possibly this:

x = input('x: ','s') 
y = input('y: ','s')
nx = length(x)
ny = length(y)
if ny > nx
  sprintf('%*s',ny,x)
elseif nx > ny
  sprintf('%*s',nx,y)
else
  display('nx=ny')
end

Or possibly this:

x = input('x: ','s') 
y = input('y: ','s')
nx = length(x)
ny = length(y)
if ny > nx
  sprintf('%s',x)
elseif nx > ny
  sprintf('%s',y)
else
  display('nx=ny')
end
