Given the following recursive function definition, what is the stopping case?

void towers$($char source, char dest, char help, int numDisks$)$

$\{$

if$($numDisks $<mtext></mtext><mn>1</mn><mi>)</mi>$

$\{$

return;

$\}$

else

$\{$

towers$($source$,$ help,dest,numDisks $-1)$;

cout $$ "Move disk from $"$ source $<mtext></mtext><mi>"</mi>$ to $"$ dest $$ endl;

towers$($help$,$dest,source,numDisks $-1)$;

$\}$

$\}$

numDisks $==1$

numDisks $>1$

numDisks $<mtext></mtext><mn>1</mn>$

numDisks $=0$
