Don't Care & Can't Happen $-$ Example $5$

$f(w,x,y,z,z1)={\displaystyle \underset{?}{\overset{?}{}}}(0,1,4,5,7,15,20,21,22,23,24,26,28,30,31)$

$D(w,x,y,z,z1)={\displaystyle \underset{?}{\overset{?}{}}}(2,8,10,16,17,18)$

Simplify the function by applying k$-$map to the $1\text{'}$s$.$Don't Care & Can't Happen $-$ Example $2$
