Question $20$

Create a control flow graph for the following code and calculate the cyclomatic complexity.

Begin

Int $x,y,$ power;

Float $z$;

input $(x,y)$;

If $(y<mn\; id="EditorElement\_341187">0</mn><mi\; id="EditorElement\_341189">)</mi>$

power$=-$y;

else

power$=$y;

$z=1$;

while $($power$!=0)\{$

$z=z^{**}x$;

power$=$power$-1$;

$\}$

If $(y<mn\; id="EditorElement\_341049">0</mn><mi\; id="EditorElement\_341051">)</mi>$

$Z=\frac{1}{z}$;

Output $($z$)$;

end

please anser it as soon as possible and make diagram in sny software on computer not on paper so that i can paste it in exam
