Consider the following Python code snippet.

$\operatorname{def} f(a, b)$ :

if ( $a==0$ ):

return b

$$ \begin{aligned} &\begin{aligned} & \text { if }(\mathrm{a} \% 2==1) \text { : } \\ & \text { return } 2 * f((a-1) / 2, b) \\ & \text { return } b+f(a-1, b) \\ & \operatorname{print}(f(15,10)) \end{aligned}\\ &\text { The value printed by the code snippet is__________ } \end{aligned} $$

Consider the following pseudocode.

Create empty stack S

set $x=0$, flag $=0$, sum $=0$

Push $x$ onto $S$

while ( $S$ is not empty) $\{$

if (flag equals 0){

Set $x=x+1$

Push $x$ onto S}

if ( $x$ equals 8 ):

Set flag $=1$

if (flag equals 1){

$x=\operatorname{Pop}(\mathrm{S})$

if ( $x$ is odd):

Pop (S)

Set sum $=\operatorname{sum}+\mathrm{x}\}$

}

Output sum

The value of sum output by a program executing the above pseudocode is________
