It is very obvious above condition will not work if output
after multiplying by 7 is not 8 bit. In that case, if you
consider 64*7=448 which is 111000000 and a 9bit number.
Thus, there is an overflow. Even a normal decimal
calculation, restricted to 8 bit will not give a right answer.
In other words, any n-bit number whose multiplication with 7
is an n-bit number, the above solution will work otherwise,
overflow will occur.
For 8 bit no. max x<=(255/7)<=36.
