main is getting called recursively, for each call 1 stack frame will be
created. the lowest stack will have the value i = 9, and top frame will have
the value i=1.
so, when i is 1 in the last call of main, when it goes to while(--i>0) st,
i becomes 0, nd so it willn't go further in the function. From here it will
start executing next st, which is the printf st, here value of i is 0, so
will print 0. After this, this frames gets removed nd the frames below this
will be executed in the same way.
so the output will be 012345678
