I am trying to solve this question but can't simplify this further.
Question: $$ 2^{\lfloor log_2{(x)} + \frac{1}{2} \rfloor} = 2^{\lfloor log_2(x-2^{\lfloor{ log_2{(\frac{x}{2})} + \frac{1}{2}}\rfloor}) + \frac{1}{2}\rfloor} + 2^{\lfloor log_2{(\frac{x}{2})+\frac{1}{2}}\rfloor}$$ My first step
$$ = 2^{\lfloor{log_2{(x - 2^{\lfloor{log_2{(x)} + \frac{1}{2}-1}\rfloor})} + \frac{1}{2} }\rfloor} + 2^{\lfloor{log_2{(x) + \frac{1}{2} - 1}}\rfloor} $$
as : $log_2(x) + \frac{1}{2} = \lfloor{log_2(x) + \frac{1}{2}}\rfloor + r $
Then I rewrite $\lfloor{log_2(x) + \frac{1}{2}}\rfloor = log_2(x) + \frac{1}{2} - r $
So : $ 2^{\lfloor{log_2{(x)} + \frac{1}{2}}\rfloor} = 2^{log_2{(x)} + \frac{1}{2} -r} = x \cdot 2^{v}$ where $v = \frac{1}{2} - r$
So that
$$ 2^{\lfloor log_2{(x)} + \frac{1}{2} \rfloor} = 2^{\lfloor{log_2{(x - x\cdot2^{v-1} )} + \frac{1}{2}}\rfloor} + x \cdot 2^{v-1} $$
$$ = 2^{\lfloor{log_2{(x(1 - 2^{v-1}) )} + \frac{1}{2}}\rfloor} + x \cdot 2^{v-1}$$
$$ = 2^{\lfloor{log_2{(x)}+ \frac{1}{2} + log_2{(1-2^{v-1})} }\rfloor} + x \cdot 2^{v-1} $$ I'm stuck here. Can anyone help?
